CVE-2025-62148 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Robots.txt rewrite plugin developed by Eugen Bobrowski, affecting versions up to 1.6.1. CSRF vulnerabilities occur when a web application does not adequately verify that requests modifying state originate from legitimate users, allowing attackers to craft malicious requests that execute unwanted actions on behalf of authenticated users. In this case, the Robots.txt rewrite plugin lacks sufficient CSRF protections, enabling attackers to induce users to unknowingly submit requests that alter the robots.txt file or related configurations. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as clicking a malicious link or visiting a crafted webpage. The impact is limited to integrity (I:L) with no confidentiality or availability impact. No patches or exploit code are currently available, and the vulnerability was published on December 31, 2025. The plugin is commonly used to manage robots.txt files, which control search engine crawling behavior, so unauthorized changes could affect SEO or site indexing. The vulnerability is classified under CWE-352, indicating a failure to implement anti-CSRF tokens or equivalent protections. Given the medium CVSS score of 4.3, the threat is moderate but warrants timely remediation to prevent misuse.

For European organizations, exploitation of this CSRF vulnerability could lead to unauthorized modifications of robots.txt files, potentially disrupting search engine indexing and SEO strategies, which can affect online visibility and traffic. While the vulnerability does not compromise sensitive data or system availability, integrity violations could undermine trust in web content management and lead to reputational damage. Organizations relying heavily on web presence for business operations, marketing, or e-commerce may experience indirect financial impacts due to altered site crawling behavior. Additionally, attackers could leverage this vulnerability as part of a broader attack chain to manipulate site behavior or mislead search engines. The absence of known exploits reduces immediate risk, but the widespread use of the plugin in European web infrastructure means that the threat could escalate if weaponized. Compliance with data protection and cybersecurity regulations in Europe, such as GDPR, may also require prompt mitigation to demonstrate due diligence in securing web assets.

To mitigate this vulnerability, organizations should first verify if they use the Eugen Bobrowski Robots.txt rewrite plugin and identify affected versions (up to 1.6.1). Although no official patches are currently available, users should monitor vendor communications for updates and apply patches promptly once released. In the interim, implement web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the plugin's endpoints. Developers and administrators should ensure that all state-changing requests include anti-CSRF tokens and validate the Origin and Referer headers to confirm legitimate request sources. Restrict access to plugin configuration interfaces to trusted users and consider additional authentication mechanisms such as multi-factor authentication (MFA) to reduce risk. Regularly audit web server logs for anomalous requests that could indicate exploitation attempts. Finally, educate users about the risks of clicking unknown links or visiting untrusted websites to reduce the likelihood of successful CSRF attacks requiring user interaction.
