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: https://cve.now/CVE-2026-115934 ### 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.
