## 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.

Weakness: CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program)
