Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: REST API endpoints were registered using permissive authorization schemas, allowing unauthenticated users to access sensitive administrative endpoints and configurations. Developers must ensure 'everyone' or empty permission handlers are not used for privileged APIs.
Deserialization: The use of standard 'maybe_unserialize' on untrusted import data allowed PHP Object Injection (POI) attacks, which can lead to remote code execution. Untrusted input must never be processed using native PHP unserialization.
Broken Access Control: Missing capability checks on the AI-generated image deletion REST endpoints allowed unauthorized users to invoke destructive functions such as post and attachment deletion.
