AI-summarised brief · reviewed before publication

Patchstack reported active exploitation of a CVSS 10.0 vulnerability in the Bricksforge WordPress plugin (CVE‑2026‑85097). The flaw, present in versions through 3.1.8.9, lets unauthenticated attackers upload a GIF/PHP polyglot, then manipulate the ‘temporaryFileUploads’ URL field to execute arbitrary PHP code via the plugin’s form‑submission endpoints. Exploits were first seen on Oct. 7, 2026, targeting the REST API (/wp‑json/bricksforge/v1/form_submit) and admin‑ajax.php actions, using varied PHP extensions and encodings to bypass filters. Patchstack observed 63 source IPs, with automated patterns suggesting rotating proxies. Bricksforge released a fix in version 3.1.8.10, and users are urged to upgrade to 4.0.1 and monitor the affected endpoints for suspicious activity. Security researchers noted that sites could be used to host web shells, steal credentials, and launch attacks visitors.
