CVE-2025-49964: 
WordPress vulnerability analysis and mitigation

CVE-2025-49964 is a Cross-Site Request Forgery (CSRF) vulnerability in the WordPress ClipLink plugin by indgeek, affecting all versions up to and including 1.1. The vulnerability was reported on May 20, 2025, and publicly disclosed on June 19–20, 2025. It carries a CVSS v3.1 base score of 4.3 (Medium) (Patchstack). As of the time of disclosure, no official patch has been released by the plugin developer (Patchstack).

The vulnerability is classified as CWE-352 (Cross-Site Request Forgery), arising from insufficient or absent CSRF token validation in the ClipLink WordPress plugin. An unauthenticated attacker can craft a malicious request or page that, when visited by an authenticated privileged user, causes the user's browser to submit unauthorized actions to the WordPress site on their behalf. Exploitation requires user interaction — specifically, a privileged user must be tricked into clicking a malicious link or visiting a crafted page (Patchstack).

Successful exploitation allows a malicious actor to force higher-privileged WordPress users (such as administrators) to execute unwanted actions under their current authentication context, potentially modifying plugin settings or site content without their knowledge. The confidentiality impact is none, availability impact is none, and integrity impact is low, limiting the practical damage to unauthorized state changes within the plugin's scope (Patchstack).

No evidence of active in-the-wild exploitation has been reported for this vulnerability. The EPSS score is approximately 0.016% (0.000160), indicating a very low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No public proof-of-concept exploit code has been identified (Patchstack).

1. Reconnaissance: Identify WordPress sites running the ClipLink plugin version 1.1 or earlier, using tools like WPScan or by inspecting publicly accessible WordPress plugin directories.
2. Craft malicious request: Construct an HTML page or link containing a forged HTTP request targeting a sensitive ClipLink plugin action endpoint (e.g., a settings update or link management function) without a valid CSRF nonce.
3. Social engineering: Deliver the malicious link or page to a logged-in WordPress administrator or privileged user via phishing email, comment, or other social engineering vector.
4. Trigger exploitation: When the privileged user visits the crafted page or clicks the link, their browser automatically submits the forged request with their active session credentials, causing the plugin to execute the unauthorized action on their behalf (Patchstack).

• Logs: WordPress access logs showing unexpected POST requests to ClipLink plugin endpoints from unusual referrer URLs or with no referrer header, particularly from IP addresses not associated with legitimate administrators.
• Application: Unexpected changes to ClipLink plugin settings or link configurations without corresponding administrator activity in WordPress audit logs.
• Network: Requests to WordPress admin-ajax.php or plugin-specific endpoints originating from external or unfamiliar sources coinciding with an authenticated admin session.

As of the disclosure date, no official patch has been released by the plugin developer for ClipLink version 1.1 or earlier. Site administrators are advised to deactivate and remove the ClipLink plugin until a patched version is available. As a compensating control, Patchstack's virtual patching feature can provide immediate mitigation for Patchstack customers. Restricting access to the WordPress admin area via IP allowlisting can also reduce exposure (Patchstack).

Wordfence included CVE-2025-49964 in its weekly WordPress vulnerability report for the period of June 16–22, 2025, noting it as part of a broader set of plugin vulnerabilities disclosed that week (Wordfence). Patchstack classified the vulnerability as low priority with no impactful threat, and no significant broader media coverage or researcher commentary has been identified.
