Password Protected <= 2.7.11 - Unauthenticated Authorization Bypass via IP Address Spoofing

Improper Authorization
CVE CVE-2025-11244
CVSS Low (3.7)
Publicly Published October 24, 2025
Last Updated October 25, 2025
Researcher Dmitrii Ignatyev
Description

The Password Protected plugin for WordPress is vulnerable to authorization bypass via IP address spoofing in all versions up to, and including, 2.7.11. This is due to the plugin trusting client-controlled HTTP headers (such as X-Forwarded-For, HTTP_CLIENT_IP, and similar headers) to determine user IP addresses in the `pp_get_ip_address()` function when the "Use transients" feature is enabled. This makes it possible for attackers to bypass authorization by spoofing these headers with the IP address of a legitimately authenticated user, granted the "Use transients" option is enabled (non-default configuration) and the site is not behind a CDN or reverse proxy that overwrites these headers.
