- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 1 GitHub repo listed by PoC-in-GitHub
- Published: 2025-07-31 · Updated: 2025-07-31

## Affected

- tigroumeow AI Engine: from 2.9.3, through 2.9.4

## Description

The AI Engine plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the rest_simpleFileUpload() function in versions 2.9.3 and 2.9.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server when the REST API is enabled, which may make remote code execution possible.
