CVE-2026-86707: CWE-287 Improper Authentication in Private Feed Key
The Private Feed Key WordPress plugin versions 0 through 0.1 contains an authentication flaw where it does not properly verify that the key used to authenticate a feed request was actually issued by the plugin. Instead, it matches any stored user metadata value, allowing unauthenticated attackers to log in as any user, including administrators.
