What is CVE-2026-9810?

The AI Copilot WordPress plugin versions prior to 1.5.4 feature a critical OAuth access token vulnerability. This issue arises from the plugin's failure to correctly bind OAuth access tokens to individual WordPress users, resulting in the capability for unauthenticated attackers to exploit the public OAuth flow. Successful exploitation allows these attackers to perform privileged actions as administrators, such as creating arbitrary users and escalating roles, thereby posing a significant risk to site security.

Affected Version(s)

AI Copilot 0 < 1.5.4

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.
