Questions about CVE-2026-115934
Is CVE-2026-115934 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The bug is an SQL injection that lets stacked SQL statements run because PDO runs with emulated prepares. The impact is unauthenticated read and write access to the application database, and an attacker can escalate to administrator privileges by setting the admin flag on user ID 1.Source: hckrt.com
Which versions are affected by CVE-2026-115934?
craftcms/cms (Packagist): from 5.0.0 before 5.11.2; from 4.0.0 before 4.18.9.Source: cve.now feed data
Am I affected, and how do I check?
Craft CMS versions from 4.0.0 up to but not including 4.18.9, and from 5.0.0 up to but not including 5.11.2, are in scope, in setups where PDO runs with emulated prepares. To check, look at the installed Craft CMS version and at whether PDO emulated prepares is enabled in the PHP configuration.Source: hckrt.com
How do I fix CVE-2026-115934?
Upgrade to 4.18.9 if you run the 4.x line, or to 5.11.2 if you run the 5.x line. The facts give no other workaround.Source: hckrt.com
