CVE-2026-9082: Drupal Core SQL Injection Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run Drupal Core. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-05-22, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-05-27; treat that as the outer limit, not the target.
• EPSS 15.7%, percentile 97: FIRST’s model estimates a 15.7% chance of exploitation activity in the next 30 days, higher than 97% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes drupal/core (Composer (PHP)) >= 8.9.0, < 10.4.10, fixed in 10.4.10; drupal/core (Composer (PHP)) >= 10.5.0, < 10.5.10, fixed in 10.5.10; drupal/core (Composer (PHP)) >= 10.6.0, < 10.6.9, fixed in 10.6.9; drupal/core (Composer (PHP)) >= 11.0.0, < 11.1.10, fixed in 11.1.10. Check your lockfile, including transitive dependencies.
