CVE-2025-12527

Page & Post Notes <= 1.3.4 - Missing Authorization to Authenticated (Subscriber+) Note Update/Deletion

Published Nov 7, 2025 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

The Page & Post Notes plugin for WordPress is vulnerable to unauthorized modification of notes due to a missing capability check on the 'yydev_notes_save_dashboard_data' function in all versions up to, and including, 1.3.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify notes.

Analysis

Technical impact

The Page & Post Notes plugin contains a missing capability check on the 'yydev_notes_save_dashboard_data' function in all releases up to 1.3.4. Authenticated users with Subscriber-level access or higher can exploit this flaw to modify or delete notes stored by the plugin. The change of note content can alter information presented to site visitors, compromising content integrity.

Affected Systems

The affected system is the Page & Post Notes WordPress plugin developed by yydevelopment. All releases up to and including version 1.3.4 are vulnerable; site administrators should verify the installed plugin version.

Risk and Exploitability

The CVSS score of 4.3 indicates medium severity. The EPSS score of less than 1% suggests a very low likelihood of exploitation in the wild, and the vulnerability is not listed in the CISA KEV catalog. Attackers must be authenticated, with at least Subscriber privileges, to exploit the flaw by invoking the backend endpoint that processes note updates or deletions.

OpenCVE Recommended Actions

Upgrade Page & Post Notes to any version newer than 1.3.4 that includes the missing capability check.
Restrict edit rights for Subscriber and lower roles by removing the custom capability used by the plugin (yydev_notes_save_dashboard_data), ensuring only Administrators can perform note modifications.
Monitor site logs for attempts to modify notes and verify that unauthorized edit attempts are blocked by the applied restrictions.
