    Issue
    Impact Under certain conditions, an authenticated user could manage MCP API keys outside their intended account allowing an attacker to escalate privileges through account takeover. Applications that do not use @payloadcms/plugin-mcp are not affected. Patches Users should upgrade to @payloadcms/plugin-mcp version 3.88.0 or later. Workarounds Upgrading is recommended. Until then, disable the MCP plugin or restrict MCP API-key management to trusted users.

    Recommended action: Upgrade to 3.88.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
