Details

Problem

Semgrep flagged line 881 in src/contextforge_memory/main.py with:

"Detected a python logger call with a potential hardcoded secret 'API key present: %s' being logged"

While this was a false positive (we're only logging a boolean, not the actual key), the message could be clearer and should follow security best practices.

Solution

Changed the log message from:

logger.info("API key present: %s", bool(API_KEY and API_KEY.strip()))

To:

logger.info("Authentication configured: %s", bool(API_KEY and API_KEY.strip()))

Verification

• ✅ Semgrep scan now shows 0 findings (previously 1 finding)
• ✅ Application still starts correctly with/without API key
• ✅ No linting errors introduced
• ✅ All pre-commit hooks pass

Impact

• Minimal: Single line change to a log message
• No functional changes to authentication or API key handling
• Improves code security scan compliance

Title Check	✅ Passed	The PR title "fix: resolve Semgrep security warning for API key logging" is directly related to the main change in the changeset. The title accurately describes the primary purpose: addressing a Semgrep security finding that flagged potential secrets in logging by changing a single log message from "API key present: %s" to "Authentication configured: %s". The title is concise, specific, and uses a conventional "fix:" prefix appropriate for a bug fix. It clearly conveys what was fixed and why, allowing teammates scanning history to immediately understand the security-focused intent without ambiguity.

881-881: Well done—this change appropriately addresses the Semgrep security warning.

The updated log message ("Authentication configured" vs. "API key present") improves clarity while eliminating unnecessary references to "API key" in logs. The logged value remains a safe boolean (bool(API_KEY and API_KEY.strip())), never exposing the actual secret. This aligns with best practices for sanitizing log data and maintaining security posture.
