CVE-2025-30946 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Michael Cannon Custom Bulk/Quick Edit plugin, affecting versions up to 1.6.10. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability exists because the plugin does not adequately verify that requests to perform bulk or quick edit operations originate from legitimate users or trusted sources. The vulnerability is exploitable remotely (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as the victim visiting a malicious website while authenticated to the vulnerable application. The impact is limited to integrity (I:L), meaning the attacker could potentially modify data or perform unauthorized edits via the bulk/quick edit functionality, but confidentiality and availability are not affected. The scope is unchanged (S:U), indicating the vulnerability affects only the vulnerable component without impacting other components or systems. No known exploits are currently in the wild, and no patches have been linked yet. The CVSS score is 4.3 (medium severity), reflecting the moderate risk posed by this vulnerability. Since the affected product is a plugin likely used in content management systems or similar web platforms, the vulnerability could be leveraged to alter content or settings without user consent, potentially leading to data integrity issues or unauthorized changes in website content or configurations.

For European organizations using the Michael Cannon Custom Bulk/Quick Edit plugin, this vulnerability could lead to unauthorized modifications of website content or configurations if an attacker successfully tricks an authenticated user into executing malicious requests. This could undermine the integrity of publicly visible information, disrupt business operations, or damage organizational reputation. Although the vulnerability does not directly compromise confidentiality or availability, unauthorized content changes could have legal or compliance implications, especially under regulations such as GDPR if personal data is involved or if misinformation is published. Organizations relying on this plugin for managing bulk edits or quick content updates should be aware that attackers could exploit this flaw to manipulate data silently, potentially leading to misinformation or operational inconsistencies. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability, increasing the risk in environments with less security awareness.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately review and apply any available patches or updates from the plugin vendor once released. 2) If patches are not yet available, consider disabling the Custom Bulk/Quick Edit plugin or restricting its use to trusted administrators only. 3) Implement anti-CSRF tokens in all forms and requests related to bulk or quick edit operations to ensure requests are legitimate. 4) Enforce strict Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests. 5) Educate users and administrators about phishing and social engineering tactics to reduce the likelihood of user interaction exploitation. 6) Monitor web server and application logs for unusual bulk edit activities or unexpected requests originating from external sources. 7) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the affected plugin endpoints. 8) Review user privilege assignments to ensure only necessary users have access to bulk/quick edit functionalities, minimizing the attack surface.
