Add cve-2026-9082 detection module (SQLi in Drupal) - #1685
Conversation
Summary by CodeRabbit
WalkthroughChangesDrupal CVE-2026-9082 vulnerability detection
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new Drupal vulnerability detector currently treats any HTTP 500 response from the login endpoint as a confirmed CVE detection, which can incorrectly flag unrelated application or database failures. The detection should require an injection-specific response or baseline comparison before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 86-92: Update the response detection conditions for the
/user/login check so an HTTP 500 alone cannot trigger vulnerability reporting.
Require an injection-specific response signature or compare the injected request
with a non-injected baseline before allowing the detection to be logged.

Do not report a vulnerability from an HTTP 500 alone.
Lines 90-91 match every internal server error from /user/login. A broken Drupal module, database outage, or unrelated application error will produce a false positive. Require an injection-specific response signature or compare this request with a non-injected baseline before logging detection.

When any HTTP service returns 500 for the malformed JSON sent to /user/login—for example because that route has an unrelated server error—this condition records a critical CVE-2026-9082 finding even though no SQL injection was demonstrated. Unlike the JSON:API probe, it checks neither a Drupal-specific response nor an injected marker, so a baseline comparison or other vulnerability-specific signal is needed to prevent false positives.

This commit adds the detector and its response-matching behavior without any automated test covering the generated requests or vulnerable and non-vulnerable responses. Add focused tests for both endpoints, including negative responses, so later payload or matching changes cannot silently turn this security result into a false positive or false negative.
