CVE-2026-9810
Published: July 17, 2026· Updated: Jul 17, 2026
Official Description
The AI Copilot WordPress plugin before 1.5.4 does not bind OAuth access tokens to a WordPress user, and accepts any valid token as an administrator session, allowing unauthenticated attackers who complete the public OAuth flow to execute privileged MCP tools as an administrator, including arbitrary user creation and role escalation.
Risk Analysis
This critical vulnerability in the AI Copilot WordPress plugin allows unauthenticated attackers to gain administrator privileges. The plugin fails to bind OAuth access tokens to specific WordPress users, treating any valid token as an administrator session. With a CVSS score of 9.8, this flaw poses a severe risk, but there is no information on exploitation likelihood (EPSS) or confirmed exploitation (KEV).
No public exploit is known for this vulnerability. It is remotely exploitable without authentication and with low attack complexity.
Update the AI Copilot WordPress plugin to version 1.5.4 or later. Ensure that OAuth access tokens are properly bound to specific user accounts and that administrative actions require appropriate user authentication and authorization checks.
Technical Analysis
CVE-2026-9810 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
