CVE-2025-9878, 25 Aug 2026
The PPWP - Password Protect WordPress | #1 Most-Reviewed Password Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ppwp' shortcode in all versions up to, and including, 1.9.21 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
CVE-2026-0551, 23 Aug 2026
The PPWP - Password Protect Pages plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.9.18 via deserialization of untrusted input from the 'post_protection_roles' vulnerable parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. CVE record
CVE-2026-3639, 13 Aug 2026
The PPWP - Password Protect Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `ppwp` shortcode attributes in all versions up to, and including, 1.9.21 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
CVE-2025-5998, 14 Aug 2025
The PPWP - Password Protect Pages WordPress plugin before version 1.9.11 allows to put the site content behind a password authorization, however users with subscriber or greater roles can view content via the REST API. CVE record
CVE-2024-11280, 17 Dec 2024
The PPWP - Password Protect Pages plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.9.5 via the WordPress core search feature. This makes it possible for unauthenticated attackers to extract sensitive data from posts that have been restricted to higher-level roles such as administrator. CVE record
CVE-2024-0620, 29 Feb 2024
The PPWP - Password Protect Pages plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.8.9 via API. This makes it possible for unauthenticated attackers to obtain post titles, IDs, slugs as well as other information including for password-protected posts. CVE record
CVE-2022-4626, 6 Feb 2023
The PPWP WordPress plugin before 1.8.6 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. CVE record

What to do if you run PPWP

If you run PPWP, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.

If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
