A Cross-Site Request Forgery (CSRF) vulnerability in the Jerry Rietveld Call Now Button plugin allows attackers to perform actions on behalf of authenticated users without their consent. This issue affects all versions of the Call Now Button plugin from n/a through version 1.4.13. The CVSS score for this vulnerability is 4.3, indicating a medium severity level, which necessitates attention to mitigate potential risks.
Risk to organizations includes unauthorized actions being executed on behalf of legitimate users, potentially leading to data exposure or manipulation. Given that this vulnerability requires user interaction to exploit, its exploitation may be limited, but it still poses a significant risk, particularly if users are misled into performing harmful actions.
Organizations should prioritize patching immediately as part of their security measures to prevent exploitation. The vulnerability was published on January 24, 2025, and remains in a deferred status, indicating that it has not yet been fully addressed by all affected parties.
At present, there is no known public exploit or proof of concept available, but organizations should remain vigilant and apply recommended updates as they become available.
Vulnerability Details
This vulnerability allows Cross-Site Request Forgery (CSRF) in the Call Now Button plugin, which is utilized in WordPress. The CVSS score of 4.3 designates it as medium severity due to its potential for unauthorized actions when exploited.
The vulnerability impacts versions up to 1.4.13 of the plugin, and it has a CWE classification of CWE-352. The publication date for this vulnerability was January 24, 2025.
Technical Analysis
The root cause of the vulnerability lies in inadequate validation of requests, which allows attackers to trick users into issuing requests that they did not intend. The attack vector is classified as NETWORK, with low complexity and no privileges required for exploitation. User interaction is required to trigger the CSRF attack.
The impact is primarily on availability, indicating that while there is no confidentiality or integrity impact, the user may be manipulated into performing unwanted actions, which can affect the overall user experience.
Risk & Impact Analysis
Organizations using the Call Now Button plugin should be aware of the potential risks associated with this vulnerability. While it requires user interaction to exploit, the possibility of unauthorized actions raises concerns about user trust and data integrity. The risk is amplified if users are unaware of the vulnerability.
Given the CVSS score of 4.3, organizations should address the vulnerability in their priority patch cycle. The potential for exploitation, though currently low, can lead to significant consequences if not managed properly.
