WordPress vulnerability analysis and mitigation

The Page & Post Notes plugin for WordPress contains a missing authorization vulnerability (CVE-2025-12527) discovered in November 2025. The vulnerability affects all versions up to and including 1.3.4 and stems from a missing capability check on the 'yydevnotessavedashboarddata' function. This security flaw allows authenticated users with Subscriber-level access or higher to modify notes without proper authorization (NVD).

The vulnerability is classified as CWE-862 (Missing Authorization) with a CVSS v3.1 base score of 4.3 (Medium) and vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N. The security flaw exists in the WordPress plugin's function 'yydevnotessavedashboarddata' which lacks proper capability checks, allowing users with insufficient privileges to modify notes (Wordfence, Rapid7).

The vulnerability allows authenticated attackers with Subscriber-level access and above to modify notes within the WordPress installation. This could lead to unauthorized modification of content and potential information integrity issues (NVD).

The vulnerability has been patched in version 1.3.5 of the Page & Post Notes plugin. The update implements proper security checks by ensuring users have the necessary privileges to edit posts before allowing them to save notes. Users are advised to update to version 1.3.5 or later (WordPress Plugin).
