CVE-2025-46513 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Codebangers All in One Time Clock Lite plugin, affecting versions up to 1.3.324. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application in which they are currently authenticated, thereby performing unauthorized actions without the user's consent. In this case, the vulnerable plugin is used for time tracking and attendance management, typically integrated into WordPress environments. The vulnerability allows attackers to craft malicious web requests that, when executed by an authenticated user, can manipulate time clock entries or related settings without proper authorization. The absence of effective anti-CSRF tokens or validation mechanisms in the plugin's request handling is the root cause. Although no known exploits are currently reported in the wild, the vulnerability's presence in a widely used time tracking plugin poses a risk of unauthorized data manipulation or disruption of attendance records. Given that the plugin operates within authenticated sessions, exploitation requires the victim to be logged into the affected system, but no additional user interaction beyond visiting a malicious page is necessary. The vulnerability does not directly expose sensitive data but can compromise data integrity and availability of attendance records, potentially impacting payroll and operational processes.

For European organizations, the exploitation of this CSRF vulnerability could lead to unauthorized modification or deletion of attendance and time tracking data, undermining the integrity of employee work records. This can result in payroll inaccuracies, compliance violations with labor regulations, and operational disruptions. Organizations relying on the affected plugin for workforce management may face challenges in auditing and verifying employee hours, which could have legal and financial repercussions. Additionally, if attackers manipulate time records to create fraudulent entries, this could facilitate insider threats or financial fraud. The impact is particularly significant for sectors with strict labor compliance requirements such as manufacturing, healthcare, and public administration. While confidentiality impact is limited, the integrity and availability of critical HR data are at risk. The medium severity rating reflects the moderate ease of exploitation (requiring authenticated sessions but no complex user interaction) and the potential operational impact on affected organizations.

To mitigate this vulnerability, organizations should prioritize updating the Codebangers All in One Time Clock Lite plugin to a patched version once available. In the absence of an official patch, administrators can implement the following specific measures: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious CSRF-like requests targeting the plugin's endpoints. 2) Enforce strict Content Security Policy (CSP) headers to limit the domains from which requests can originate, reducing the risk of CSRF attacks. 3) Implement additional server-side validation to verify the origin and intent of POST requests related to time clock entries, such as checking HTTP Referer headers or requiring re-authentication for sensitive actions. 4) Educate users to avoid clicking on untrusted links while logged into the time clock system. 5) Monitor logs for unusual activity patterns indicative of CSRF exploitation attempts, such as unexpected changes in attendance records. 6) Consider isolating the time clock system behind VPN or internal network access controls to limit exposure. These targeted mitigations go beyond generic advice by focusing on compensating controls until an official patch is released.
