CVE-2025-13558

Blog2Social <= 8.7.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Trashing

Published Nov 25, 2025 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed

Description

The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'deleteUserCcDraftPost' function in all versions up to, and including, 8.7.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change the status of arbitrary posts to trash.

Analysis

Technical impact

The Blog2Social plugin for WordPress contains a missing capability check on the deleteUserCcDraftPost function. As a result, any authenticated user with Subscriber level or higher can invoke this AJAX action and change the status of any post to trash. This flaw permits unauthorized deletion or defacement of content without requiring elevated privileges. The weakness is classified as Missing Authorization (CWE-862).

Affected Systems

All installations of Blog2Social for WordPress up to and including version 8.7.0 are affected. Users running these versions should confirm their deployed plugin version and plan an upgrade accordingly.

Risk and Exploitability

The CVSS score of 5.4 indicates moderate severity, but the EPSS score of less than 1% suggests a very low current probability of exploitation. Attackers need only authentication with Subscriber-level access or higher to trigger the vulnerability. The lack of a required high-level privilege and the absence in the CISA KEV list reduce the immediate threat, yet the potential to erase or disrupt content makes it worth addressing promptly.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade Blog2Social to the latest version that includes the authorization fix.

Verify that the WordPress core and other plugins remain up to date and that all user roles are correctly assigned to prevent accidental privilege escalation.
