What is CVE-2026-88994?
CVE-2026-88994 is a medium-severity path traversal vulnerability in Unknown All Bootstrap Blocks, published on 18 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
