Contributor Insecure Direct Object References (IDOR) in PPWP <= 1.9.19 versions.
AnalysisAI
Password Protect WordPress Page (PPWP) plugin versions up to and including 1.9.19 expose an Insecure Direct Object Reference (IDOR) flaw exploitable by authenticated Contributors, enabling unauthorized modification of password-protected page objects outside the attacker's authorized scope. The plugin fails to validate that the user-supplied object reference belongs to a resource the requesting Contributor is authorized to manage, as classified under CWE-639. No public exploit code has been identified and the vulnerability is not listed in CISA KEV; real-world risk is meaningfully constrained by the Contributor authentication prerequisite.
Technical ContextAI
PPWP is a WordPress plugin that provides granular password protection for individual pages and posts. CWE-639 (Authorization Bypass Through User-Controlled Key) indicates the plugin accepts user-controllable identifiers - such as page IDs or protection record IDs - in requests without verifying that the authenticated user is authorized to operate on the referenced object. In the WordPress permission model, Contributors can create and edit their own unpublished content but cannot manage others' posts or site-wide settings; the IDOR collapses this boundary by allowing a Contributor to reference and manipulate protection configurations tied to objects owned by higher-privileged users. The vulnerability was discovered and reported by Patchstack (audit@patchstack.com), a dedicated WordPress security intelligence platform, and is tracked as EUVD-2026-39750 in the ENISA EUVD registry. No CPE string was provided in source data; the affected software is identifiable as the 'password-protect-page' WordPress plugin slug.
RemediationAI
Users should upgrade the PPWP plugin to a version beyond 1.9.19 as soon as a patched release is confirmed via the WordPress plugin repository or the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/password-protect-page/vulnerability/wordpress-ppwp-plugin-1-9-19-insecure-direct-object-references-idor-vulnerability - a specific patched version number is not confirmed in the available source data at time of analysis. If an updated version is not yet available, the primary compensating control is to audit and restrict which users hold the Contributor role: remove Contributor accounts that are not operationally required, disable open user registration if not needed, and ensure that Contributor accounts are issued only to fully trusted individuals. Disabling the PPWP plugin entirely until patched is a viable option if the password-protection functionality is not critical, though this would remove page protections currently in place. Note that restricting Contributor roles does not affect existing authenticated sessions - active sessions should be invalidated if account compromise is suspected.
