CISA has given US federal civilian agencies a midnight Wednesday May 27 deadline to patch CVE-2026-9082, the highly critical Drupal SQL injection added to its Known Exploited Vulnerabilities catalog on Friday. Imperva says it has now observed 15,000+ attack attempts targeting nearly 6,000 individual Drupal sites across 65 countries since disclosure, with gaming and financial services taking almost half. Shadowserver tracks ~670 unpatched Drupal instances still exposed online (272 in North America, 273 in Europe). CISA's directive is mandatory only for FCEB agencies under BOD 22-01, but the agency strongly urges all organizations to patch immediately.
Drupal has issued an update to its highly critical PSA-2026-05-18 advisory confirming that exploit attempts for CVE-2026-9082 are now being detected in the wild. The bug is an SQL injection in Drupal's database abstraction API that lets unauthenticated requests trigger arbitrary SQL on sites running PostgreSQL, with possible escalation to RCE, privilege escalation, and information disclosure. Drupal rates it 23 out of 25 internally though NIST's CVSS v3 score is a mismatched 6.5. CISA added it to KEV on May 22. Affected versions cover Drupal 8.9.x and all 10.x and 11.x branches up to 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, and 11.3.10.
Drupal has shipped the highly critical core security release teased by PSA-2026-05-18. The flaw lets attackers achieve remote code execution on Drupal sites running PostgreSQL backends. Fixed versions are 11.3.10, 11.2.12, 11.1.10, 10.6.9, 10.5.10, and 10.4.10. The releases for supported branches also pull in upstream Symfony and Twig security fixes, making the upgrade essential even on MySQL deployments. Best-effort manual patches are available for end-of-life Drupal 9.5 and 8.9. Drupal 7 is not affected. The Drupal Security Team had warned that working exploits could follow within hours of disclosure, so administrators should patch now.
Drupal is releasing an emergency core security update on May 20 between 17:00 and 21:00 UTC. Pre-disclosure advisory PSA-2026-05-18 rates the issue 'highly critical' (20 of 25 on Drupal's scoring) and notes access complexity 'None' and authentication 'None' - meaning the underlying flaw is unauthenticated and easy to trigger. Patches will land for the supported 11.3.x, 11.2.x, 10.6.x, and 10.5.x branches, plus emergency patches for EOL 11.1.x and 10.4.x. Drupal 7 is not affected. Drupal 8 and 9 will only get best-effort manual patch files. The Drupal Security Team warns working exploits may follow within hours of disclosure.
