Subscriber Broken Access Control in Push Notification for Post and BuddyPress <= 3.20 versions.
AnalysisAI
Broken access control in the Push Notification for Post and BuddyPress WordPress plugin (version <= 3.20) allows authenticated users with subscriber-level privileges to perform actions restricted to higher-privileged roles, resulting in unauthorized read and write access. Exploitation requires only a valid WordPress subscriber account on the target site, making it relevant wherever the plugin is installed on community-oriented or membership-based WordPress sites running BuddyPress. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress subscriber-level (or higher) account on the target site; completely unauthenticated exploitation is not supported by the CVSS PR:L vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N indicates a network-accessible, low-complexity flaw requiring low privileges (subscriber role) and no user interaction, with limited confidentiality and integrity impact and no availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on a WordPress site running BuddyPress with open registration enabled. Using their subscriber session cookie, they send a crafted HTTP request to an insufficiently protected plugin endpoint - such as an admin-only AJAX action - bypassing the missing authorization check to read push notification subscriber lists or modify notification settings they should not control. |
| Remediation | Patch availability per vendor or Patchstack advisory should be confirmed at https://patchstack.com/database/wordpress/plugin/push-notification-for-post-and-buddypress/vulnerability/wordpress-push-notification-for-post-and-buddypress-plugin-3-20-broken-access-control-vulnerability - no specific patched version number is confirmed in currently available data, so administrators should check for a plugin update beyond version 3.20 via the WordPress plugin repository. … Detailed patch versions, workarounds, and compensating controls in full report. |
