CVSS 3.1 6.6 MEDIUMCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-88994

Published

The All Bootstrap Blocks WordPress plugin through 1.3.31 does not validate a block attribute before using it to build a filesystem path that is included at render time, allowing users with contributor-level access and above to include arbitrary local files, disclose their contents, and execute PHP where a local file containing PHP code can be reached. Exploitation requires the plugin's Lightspeed subsystem to be enabled, which is not the default.
