CVE-2025-24736 identifies a missing authorization vulnerability in the metaphorcreations Post Duplicator plugin, a tool commonly used in WordPress environments to duplicate posts for content management efficiency. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to perform actions that should be restricted. Specifically, the plugin fails to properly verify whether a user has the necessary permissions before allowing post duplication operations. This can lead to unauthorized duplication of content, potentially enabling attackers to manipulate website content, bypass content publishing workflows, or escalate privileges by creating unauthorized copies of posts. The affected versions include all releases up to and including version 2.35. No CVSS score has been assigned yet, and no public exploits have been reported, but the vulnerability is publicly disclosed and considered exploitable due to the lack of authorization checks. The issue is particularly relevant for organizations using the Post Duplicator plugin in multi-user WordPress environments where content integrity and access control are critical. Since the vulnerability does not require user interaction and can be exploited remotely by an authenticated or unauthenticated attacker depending on the plugin’s exposure, it poses a significant risk. The lack of official patches or mitigation guidance at the time of disclosure increases the urgency for organizations to implement compensating controls.

The primary impact of CVE-2025-24736 is the unauthorized duplication of posts within WordPress sites using the vulnerable Post Duplicator plugin. This can compromise content integrity by allowing attackers to create unauthorized copies of posts, potentially leading to misinformation, content spamming, or unauthorized content distribution. In environments where content duplication is tied to publishing workflows or approval processes, attackers could bypass these controls, undermining operational security. Additionally, unauthorized duplication could be leveraged as a stepping stone for privilege escalation or lateral movement within the content management system if combined with other vulnerabilities. The vulnerability affects the confidentiality and integrity of website content and may indirectly impact availability if exploited at scale to flood the system with duplicated content. Organizations relying heavily on WordPress for their web presence, especially those with multiple content editors or contributors, face increased risk of content manipulation and operational disruption.

To mitigate CVE-2025-24736, organizations should immediately review and restrict access permissions to the Post Duplicator plugin interface, ensuring only trusted and authorized users can perform duplication operations. Implement role-based access controls (RBAC) that enforce the principle of least privilege for all users interacting with the plugin. Monitor logs and audit trails for unusual duplication activities or spikes in post creation that could indicate exploitation attempts. If possible, temporarily disable the Post Duplicator plugin until a security patch or update is released by metaphorcreations. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting the plugin’s endpoints. Stay informed about vendor updates and apply patches promptly once available. Additionally, conduct regular security assessments of WordPress plugins and configurations to identify and remediate similar access control weaknesses proactively.
