What is CVE-2026-81737?

The FAQ Builder AYS WordPress plugin, prior to version 1.8.5, has a vulnerability that permits unauthenticated users to submit content without proper sanitization or escaping. This leads to the potential for Stored Cross-Site Scripting (XSS) attacks, where malicious scripts can be executed in the context of the administrator's session. The plugin's attempt to escape submitted content is ultimately compromised by a subsequent decoding step, creating a significant security risk for websites using this plugin.

Affected Version(s)

FAQ Builder AYS 1.6.3 < 1.8.5

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
