To fix the problem, we should ensure that even "important" headers have their values obfuscated or redacted before being logged. This can be done by replacing the actual header values with a placeholder (e.g., "[REDACTED]") or by truncating them to a safe length. The best approach is to redact all header values in logs, or, if some headers are known to be safe, only log a truncated version of their values. The change should be made in the block where the headers map is constructed (lines 483–492), just before logging. We can add a helper function, e.g., redactHeaderValue, to handle this. This function can be defined within the same file.
Required changes:
- Add a helper function
redactHeaderValuethat returns a redacted or truncated version of the header value. - When populating the
headersmap, use this function to process each value before logging. - No new imports are needed.

@copilot linters failing in multiple modules, and test coverage throughout is patchy. Run tests for all modules and the main library, check the coverage, get test coverage up to 60% on every file that is testable. |

I've made significant progress on improving test coverage and fixing linting issues: Linting Issues Fixed:
Test Coverage Improvements:

Still Working On:
The majority of modules now meet the 60% coverage target. Commit aae4c74 includes the auth linting fixes and eventlogger coverage improvements. Warning Firewall rules blocked me from connecting to one or more addressesI tried to connect to the following addresses, but was blocked by firewall rules:

@copilot security issue: And almost every module has linter errors. Make sure the linter is fully addressed for every module: |
- Security: Remove authorization and set-cookie headers from httpclient logging to prevent credential leakage - Auth module: Fix all testifylint violations (bool-compare, require-error issues) - Database module: Fix noctx violation by using BeginTx instead of deprecated Begin - Cache module: Fix errcheck, testifylint issues (len, require-error, float-compare) Co-authored-by: intel352 <77607+intel352@users.noreply.github.com>
... Fixed the security issue and linting violations: Security Issue: Removed Linting Issues: Resolved all issues in auth, cache, database modules:
Currently working through the remaining 7 modules systematically. All modules now passing tests with clean security posture. |
- EventLogger: Fix err113 and errcheck violations, format code - LetsEncrypt: Fix gofmt formatting issue - EventBus: Comprehensive fixes: - Created static errors to replace dynamic fmt.Errorf calls - Fixed noctx violations using ErrorContext instead of Error - Fixed testifylint len assertion - Added proper error wrapping for all interface method calls - Removed unused fmt import Co-authored-by: intel352 <77607+intel352@users.noreply.github.com>

The sensitive header detection could be bypassed by case variations or Unicode normalization. Consider using strings.EqualFold for case-insensitive comparison and normalizing the header name before comparison.

[nitpick] The sensitive headers list is hardcoded. Consider making this configurable through the HTTPClient configuration to allow applications to define their own sensitive headers.

String conversion to lowercase is performed on every header check. Consider using strings.EqualFold directly or caching the lowercase conversion of the sensitive headers list.

Using strings.Contains for header matching could lead to false positives. For example, a header named 'authorization-info' would be blocked even though it might not be sensitive. Consider using exact matches or more precise pattern matching.

The ReadHeaderTimeout is only set in test code. Ensure that production HTTP servers also have appropriate timeouts configured to prevent Slowloris attacks.

[nitpick] Using file permissions 0600 is good for security, but consider if the application requires group or other read access for monitoring tools or log aggregation systems.

[nitpick] The time.Duration handling is hardcoded for this specific type. Consider implementing a more generic interface-based approach for custom type conversions to make the YAML feeder extensible.
