Logging the admin token (and embedding it in the logged URL) leaks a credential into application logs. Since this code is being touched, please remove these log lines or redact the token (e.g., log only the last few chars) while still logging the host/port so operators can find the admin endpoint safely.

Suggested change

	logger.info("Admin token: %s", admin_token)
	logger.info("Admin URL: %s://%s:%s/?token=%s", protocol, deps.host, deps.port, admin_token)
	redacted_token = f"...{admin_token[-4:]}" if admin_token and len(admin_token) > 4 else "***"
	logger.info("Admin token (redacted): %s", redacted_token)
	logger.info("Admin URL: %s://%s:%s/", protocol, deps.host, deps.port)

AgentContainer (from x/agent_server/runtime/container.py) does not define a compositor attribute/property—only _compositor. These container.compositor references will raise AttributeError and prevent agents from being mounted into the global compositor. Expose a public compositor property on AgentContainer (preferred) or switch these references back to the existing _compositor field with appropriate type/None checks.

[Copilot]

This shutdown path tries to flush container.ui_manager, but the current AgentContainer type stored in app.state.registry has no ui_manager attribute (it has ui with ui.manager). As written, this branch will never run; either remove it or flush via container.ui.manager when present (or rely solely on close_all(), which already flushes during AgentContainer.close()).

[Copilot]

Using logging.getLevelName(log_level.upper()) is unsafe for invalid values: for unknown level names it returns a string like 'Level FOO', and file_handler.setLevel(...) will raise ValueError (not caught here). Use a mapping-based lookup (e.g., logging.getLevelNamesMapping().get(...)) and/or catch ValueError to fall back to INFO while logging the warning.

[Copilot]

These log messages still contain {container_id[:12]} / {cmd!r} brace placeholders from the old f-strings, but they are now plain strings and will be logged literally. Convert them to proper % placeholders and pass container_id / cmd as logger args so the debug logs remain accurate.

Suggested change

	logger.debug("Executing command in container {container_id[:12]}: {cmd!r} (timeout_ms=%s)", input.timeout_ms)
	logger.debug(
	"Executing command in container %.12s: %r (timeout_ms=%s)",
	container_id,
	cmd,
	input.timeout_ms,
	)

[Copilot]

Same issue as above: these messages include {container_id[:12]} brace placeholders that will be logged literally after the f-string→% conversion. Update the format string to use %s placeholders and pass the sliced container id as an argument so timeout/kill logs contain the correct context.

This method was renamed from _mount_names to mount_names, but other in-repo callers still use _mount_names() (e.g., mcp_infra/compositor/notifications_buffer.py and mcp_infra/compositor/resources_server.py). As-is, those callers will fail with AttributeError. Either update all call sites in this PR or keep a backward-compatible _mount_names alias that forwards to mount_names.

Suggested change

	async def _mount_names(self) -> list[str]:
	"""Backward-compatible alias for mount_names().
	This can be removed after all in-repo callers have been updated
	to use mount_names() instead of _mount_names().
	"""
	return await self.mount_names()

In general, to fix clear‑text logging issues, stop including potentially sensitive values directly in log messages. Either remove them, replace them with non‑sensitive identifiers, or heavily redact them.

Best targeted fix here: change the logger.info calls in K8sTokenStore.write_token so they no longer interpolate the namespace (and probably not the exact secret name either). Functionality of the method (reading/replacing/creating the secret) is unchanged; only the log message is made more generic. This keeps observability (“a secret was updated/created”) while avoiding logging where that secret lives.

Concretely in airlock/oauth/k8s_client.py:

• On line 55, replace logger.info("Updated secret %s/%s", namespace, secret_name) with a message that does not include namespace or secret_name, for example logger.info("Updated Kubernetes secret").
• On line 59, do the same for the “Created secret …” message.

No new imports, methods, or definitions are required; only the two log statements change.

---

To fix the problem, avoid logging the clear-text value of secret_name (and arguably the full namespace/secret_name pair). Instead, log only non-sensitive context (e.g., that a secret was created/updated in some namespace), or log a redacted or hashed form of the secret name that is still useful for debugging but not directly exploitable.

The best minimal change is:

• Introduce a small helper function in this file to produce a redacted representation of the secret name (e.g., first and last character plus length, or a short hash).
• Update the two logger.info calls to use this redacted string instead of the raw secret_name.
• Keep functionality intact: the Kubernetes API calls remain unchanged; only log output is altered.
• No new external dependencies are needed; we can rely on the standard library (hashlib) if we choose hashing, or just do simple string redaction.

Concretely in airlock/oauth/k8s_client.py:

• Add a helper function (e.g., _redact_secret_name) near the top of the file or inside the class to transform the secret name into a non-sensitive representation.
• Change line 55 from logger.info("Updated secret %s/%s", namespace, secret_name) to log namespace plus redacted_secret_name.
• Change line 59 from logger.info("Created secret %s/%s", namespace, secret_name) similarly.

In general, to fix clear-text logging of sensitive information, you either (a) remove the sensitive value from the log message entirely, (b) replace it with a non-sensitive identifier (e.g., a constant label or hash), or (c) redact or partially mask it before logging. Functionality of the system (managing secrets in Kubernetes) should not be affected; only the human-readable log messages need adjustment.

Here, the only problematic use is logging the namespace parameter alongside the secret_name when a secret is created. We can keep useful operational information while removing the potentially sensitive namespace by logging only the secret name and possibly a generic description instead of the full namespace/secret_name pair. The behavior of write_token (reading/creating/replacing secrets) remains unchanged.

Concretely, in airlock/oauth/k8s_client.py:

• On line 59, change:
  • logger.info("Created secret %s/%s", namespace, secret_name)
• To something that does not include namespace, such as:
  • logger.info("Created secret %s", secret_name)

We do not need new imports or helper methods; we only modify this single log call. The other log messages that include namespace (e.g., "Updated secret %s/%s" and "Deleted orphaned secret %s/%s") have not been flagged by CodeQL through this taint path and are not directly tied to the specific source considered sensitive in this alert; to keep the fix minimal and targeted, we will not alter them.

In general, to fix clear-text logging issues, remove sensitive values from log messages or replace them with non-sensitive summaries (e.g., static text, types, or redacted/hashed forms). The goal is to retain operationally useful information (that an action occurred and whether it succeeded) without leaking identifiers or secrets.

In this file, the only problematic uses are the logger.info calls that interpolate %s/%s with namespace and secret_name when creating/updating/deleting secrets. The best fix that preserves behavior is to log the operation and the actor (managed_by) but not the specific secret name or namespace. That means changing:

• Line 55: logger.info("Updated secret %s/%s", namespace, secret_name)
• Line 59: logger.info("Created secret %s/%s", namespace, secret_name)
• Line 71: logger.info("Deleted orphaned secret %s/%s", namespace, name)

to messages like:

• logger.info("Updated managed secret for %s", self._managed_by)
• logger.info("Created managed secret for %s", self._managed_by)
• logger.info("Deleted orphaned managed secret for %s", self._managed_by)

This keeps useful audit information (that the token store acted and which manager label it used), avoids introducing new imports or helpers, and does not change control flow or API interactions. No new methods or definitions are required; we only adjust the log message format strings and arguments within airlock/oauth/k8s_client.py.

General fix: Avoid logging potentially sensitive values such as Kubernetes namespaces (especially when associated with secret operations) in clear text. Either remove them from log messages, replace them with less specific information, or redact them.

Best concrete fix here: Adjust the log statement in K8sTokenStore.delete_orphaned_secrets so it no longer prints the namespace argument. We can still log that an orphaned secret was deleted and its name (or even omit the name if desired), but we should not log the full namespace/name pair that the analyzer flagged. This keeps existing behavior of the method (deleting secrets) unchanged; we only modify the log message format string and arguments.

Specific change:

• File: airlock/oauth/k8s_client.py
  • Around line 71, change:

    logger.info("Deleted orphaned secret %s/%s", namespace, name)

    to something like:

    logger.info("Deleted orphaned secret %s", name)

  • No new imports or helper methods are required.

In general: avoid logging any value that might contain sensitive data (tokens, passwords, secrets, or identifiers that could embed them). When logging is needed for debugging/operations, log non-sensitive metadata or a redacted version instead.

Best fix here: adjust the log messages in airlock/oauth/refresh.py to avoid logging the potentially sensitive name value, replacing it with non-sensitive metadata derived from the Provider instance (e.g., its class name) or with a generic placeholder. This retains useful context (“which type of provider failed”) while ensuring that any potentially sensitive identifier from configuration is not written to logs.

Concretely, in airlock/oauth/refresh.py:

• On lines 30 and 45, replace "Refreshing token for %s (expires %s)", name, token.expires_at and "Refreshed token for %s (new expiry %s)", name, new_token.expires_at with messages that don’t interpolate name. For instance, log only the expiry, or log the provider class name via type(provider).__name__.
• On line 47, change logger.exception("Failed to refresh token for %s", name) to a message that doesn’t include name, e.g., "Failed to refresh token for provider" or use type(provider).__name__ as non-sensitive context.
• No extra imports or helper methods are required; we can derive the provider’s class name inline (type(provider).__name__).
• We must not change external behavior beyond log content; the logic and control flow remain untouched.

In general, to fix clear-text logging of sensitive information, remove or redact any logs that might include passwords, tokens, or URLs that could embed those secrets. Instead, log only non-sensitive metadata such as whether an operation succeeded, or a generic tag/ID that does not by itself grant access.

For this specific case, the safest change without altering functionality is to stop logging the contents of wss_url at line 132. The log statement can be replaced with a generic debug message like "Connecting to VNC WebSocket..." which provides operational context without revealing the actual URL. No changes are needed to how the URL is used to establish the connection; only the log content must change. This requires editing skills/hetzner_vnc_screenshot/vnc_screenshot.py near line 132, replacing the existing logger.debug("Connecting to %s...", wss_url[:60]) line with a message that does not interpolate wss_url at all. No new imports, methods, or other definitions are required.

---

In general, to fix clear‑text logging of sensitive information, you reduce or remove sensitive detail from log messages, or mask/obfuscate it so logs stay useful without exposing secrets. You should ensure that tokens, passwords, private keys, and often identifiers of sensitive resources are not logged at info/error levels.

Here, the best minimal fix is to stop logging the exact secret name and namespace while keeping a useful operational message. We can change the logger.info calls to a more generic message that doesn’t interpolate cfg.secret_name or cfg.namespace. No new functions or complex logic are needed; just adjust the log message strings in _write_secret.

Concretely, in tana/token_broker/broker.py, inside _write_secret, replace:

logger.info("Updated secret %s/%s", cfg.namespace, cfg.secret_name)
...
logger.info("Created secret %s/%s", cfg.namespace, cfg.secret_name)

with messages that do not include those values, e.g.:

logger.info("Updated OAuth token Kubernetes secret")
...
logger.info("Created OAuth token Kubernetes secret")

This avoids logging the secret’s identifying information while preserving information that the operation succeeded. No additional imports or definitions are required.

In general, to fix clear-text logging of sensitive information, remove sensitive values from log messages or replace them with non-sensitive identifiers (e.g., high-level descriptions, hashes, or redacted placeholders). Maintain enough context in logs for debugging without exposing secrets or their direct identifiers.

Here, the issue is the use of cfg.namespace and cfg.secret_name in the logger.info calls in _write_secret. The best fix that preserves functionality is to log a generic success message without including the secret name/namespace (or, if you wanted, a fully redacted representation). The K8s API calls already identify which secret is being operated on; changing the log text does not affect behavior.

Concretely:

• In tana/token_broker/broker.py, in _write_secret, update:
  • logger.info("Updated secret %s/%s", cfg.namespace, cfg.secret_name)
  • logger.info("Created secret %s/%s", cfg.namespace, cfg.secret_name)
• Replace them with logs that omit or generically describe the secret, such as:
  • logger.info("Updated OAuth token secret")
  • logger.info("Created OAuth token secret")
    No new imports or helpers are needed.

In general, to fix clear-text logging of sensitive information, either stop logging the sensitive value altogether or log only non-sensitive metadata (e.g., that a secret is configured, without its identifier or contents), or mask/redact it (e.g., show only a prefix). Here, we want to keep the startup log but avoid logging cfg.secret_name directly.

The minimal, behavior-preserving change is to modify the logger.info call in main() so it no longer logs secret_name. Since the name of the secret is not necessary for basic observability, we can simply remove it from the log format string and from the argument list. No additional imports or helper methods are needed; this is a one-line change in tana/token_broker/cli.py around lines 33–38 where the log message is constructed.
