CVE-2025-14943 is an authorization bypass vulnerability classified under CWE-863 found in the Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress, affecting all versions up to 8.7.2. The vulnerability arises from improper authorization checks in the 'getShipItemFullText' function. This function validates that a user has the 'read' capability (which includes Subscriber-level users) and a valid nonce but fails to verify whether the user has permission to access the specific post requested. Consequently, authenticated users with minimal privileges can retrieve the full content of posts that are password-protected, private, or in draft status, which should normally be inaccessible to them. The flaw allows sensitive information exposure without requiring elevated privileges beyond Subscriber-level or user interaction, and it can be exploited remotely via network requests to the vulnerable WordPress site. The vulnerability does not impact the integrity or availability of the system but compromises confidentiality by leaking potentially sensitive unpublished content. No patches or official fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The CVSS v3.1 base score is 4.3, indicating a medium severity level primarily due to the confidentiality impact and ease of exploitation by low-privileged authenticated users.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive or confidential content stored in WordPress sites using the Blog2Social plugin. This could include unpublished marketing materials, internal communications, or other private data intended only for authorized personnel. Exposure of such information could lead to reputational damage, loss of competitive advantage, or compliance violations under regulations like GDPR if personal data is involved. Since the vulnerability requires only Subscriber-level authentication, it increases the attack surface, especially in environments where user registration is open or poorly controlled. The impact is limited to confidentiality, with no direct effect on system integrity or availability. However, the leakage of sensitive drafts or private posts could facilitate further targeted attacks or social engineering campaigns. Organizations relying on WordPress for content management and social media automation should assess their exposure and implement mitigations promptly to prevent data leakage.

1. Immediately restrict user registration and review user roles to ensure only trusted users have Subscriber-level or higher access. 2. Implement strict access controls and monitor for unusual access patterns to private or draft posts. 3. Temporarily disable or remove the Blog2Social plugin until an official patch is released. 4. If disabling the plugin is not feasible, consider applying custom code to enforce proper authorization checks on the 'getShipItemFullText' function, ensuring users can only access posts they are authorized to view. 5. Regularly audit WordPress plugins for updates and security advisories, and subscribe to vendor or security mailing lists for timely patch notifications. 6. Employ Web Application Firewalls (WAF) with rules to detect and block suspicious requests targeting this plugin’s endpoints. 7. Conduct internal training to raise awareness about the risks of unauthorized content exposure and the importance of role-based access control. 8. Review and sanitize sensitive content stored in drafts or private posts to minimize risk exposure.
