CVE-2025-62865

Root

Cause

The Post Cloner plugin for WordPress, version 1.0.0 and earlier, contains a missing authorization vulnerability. The software fails to properly enforce access controls on certain functions, meaning that it does not check whether a user has the required privileges before allowing an operation [1]. This is a classic broken access control flaw, classified under CWE-862 (Missing Authorization).

Exploitation

Because the plugin lacks the necessary authorization checks, any user—including those with minimal or no authentication—can potentially trigger actions intended only for higher-privileged roles such as administrators. The vulnerability is exploitable without any special prerequisites, making it easy for attackers to integrate into mass-exploit tooling [1]. No authentication token or nonce validation is performed on the vulnerable endpoint.

Impact

An attacker who successfully exploits this flaw can misuse the plugin's functionality to clone or modify posts, thereby gaining unauthorized access to content creation and editing features. This could lead to defacement, spam injection, or other content-based attacks. The CVSS v3 base score is 5.3 (Medium), reflecting the potential for unauthorized actions without requiring authentication.

Mitigation

Users are strongly advised to update the Post Cloner plugin to a patched version as soon as one becomes available. The vendor has been made aware, and the issue is documented at Patchstack [1]. If an update cannot be applied, site administrators should consider temporarily disabling the plugin or restricting access via web application firewall rules. This vulnerability is noted as being suitable for mass exploitation campaigns, so immediate action is recommended.
