Risk to organizations includes unauthorized actions that may compromise user data or lead to further exploitations within the system. Attackers may leverage this vulnerability to execute harmful scripts or redirect users to malicious sites. Given the current exploitation status as 'No' confirmed public exploit, it is crucial for organizations to implement necessary patches as soon as they are made available.
Organizations should prioritize patching immediately. Timely remediation is vital to safeguarding against potential exploits that could arise as awareness of this vulnerability spreads.
Vulnerability Details
CVE-2025-23537 is a Cross-Site Request Forgery (CSRF) vulnerability in the add custom google tag manager plugin. This vulnerability allows for stored XSS, which can be particularly damaging as it can lead to unauthorized actions being executed within the context of a user’s session. The CVSS score assigned is 7.1, reflecting its high severity. This vulnerability affects versions of the plugin from n/a to 1.0.3.
The issue was published on January 16, 2025, and is classified under CWE-352, which pertains to Cross-Site Request Forgery. Organizations using this plugin are strongly advised to monitor for any updates or patches that address this vulnerability.
Technical Analysis
The root cause of CVE-2025-23537 stems from a lack of proper validation and security checks in the plugin, which enables attackers to exploit the CSRF vulnerability. The attack vector is through network interactions, with low attack complexity. This means that attackers do not require significant effort or advanced skills to exploit the vulnerability. The user must interact with the site, as their actions can trigger the CSRF attack.
The privileges required to exploit this vulnerability are none, indicating that attackers do not need to authenticate themselves to take advantage of this security flaw. The impacts on confidentiality, integrity, and availability are all classified as low, suggesting that while there is a potential for negative consequences, they may not be catastrophic.
Risk & Impact Analysis
The deployment of the add custom google tag manager plugin in various organizations presents real-world risks. The potential for unauthorized actions through CSRF can lead to data breaches, manipulation of website content, and compromise of user trust. The blast radius could be significant if exploited, especially for organizations relying heavily on this plugin for key functionality.
Organizations must assess the urgency based on the CVSS score and the potential impact of this vulnerability. Given the current classification as high severity, it is advisable to address this vulnerability in the priority patch cycle. Organizations should remain vigilant and ready to implement mitigations as patches are released.
