Technical Analysis

CVE-2025-43835 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'wp-cyr-cho' developed by ktsvetkov. This vulnerability affects versions up to 0.1, with no specific earliest affected version stated. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request to a web application, thereby performing unwanted actions on behalf of the user without their consent. In this case, the vulnerability could enable an attacker to induce a logged-in WordPress administrator or user with sufficient privileges to execute unintended actions within the wp-cyr-cho plugin, potentially altering plugin settings or behavior. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely (AV:N), requires low attack complexity (AC:L), no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L) with no confidentiality or availability impact. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability is publicly disclosed and tracked by Patchstack and CISA enrichment, indicating recognition by security authorities. The wp-cyr-cho plugin is a WordPress plugin, which suggests that the attack surface is limited to WordPress sites using this specific plugin version. The lack of a patch means that affected sites remain vulnerable until a fix is released or mitigations are applied.

Potential Impact

For European organizations, the impact of this CSRF vulnerability depends largely on the adoption of the wp-cyr-cho plugin within their WordPress environments. If used, the vulnerability could allow attackers to manipulate plugin settings or perform unauthorized actions via forged requests, potentially leading to integrity issues such as unauthorized content changes or configuration tampering. While confidentiality and availability are not directly impacted, integrity compromises can undermine trust in affected websites and lead to reputational damage. Organizations relying on WordPress for public-facing websites or internal portals that use this plugin may face risks of unauthorized changes that could disrupt business operations or user experience. Additionally, if attackers combine this vulnerability with other weaknesses, it could facilitate more complex attack chains. Given the medium severity and requirement for user interaction, the threat is moderate but should not be ignored, especially for organizations with high web presence or regulatory requirements around website integrity and security.

Mitigation Recommendations

Since no official patch is currently available, European organizations should implement specific mitigations to reduce risk. First, disable or uninstall the wp-cyr-cho plugin if it is not essential, or replace it with a more secure alternative. For sites that must continue using the plugin, implement strict Content Security Policy (CSP) headers to limit the sources of executable scripts and reduce the risk of CSRF attacks. Employ anti-CSRF tokens or nonce mechanisms at the application level if possible, either by customizing the plugin code or using WordPress security plugins that add CSRF protections. Restrict administrative access to trusted IP addresses and enforce multi-factor authentication (MFA) to reduce the risk of session hijacking that could facilitate CSRF exploitation. Monitor web server and application logs for suspicious POST requests or unusual activity patterns. Finally, maintain up-to-date backups and prepare an incident response plan to quickly remediate any unauthorized changes resulting from exploitation.
