CVE-2025-4199 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Abundatrade Plugin for WordPress, developed by withinboredom. This vulnerability exists in all versions up to and including 1.8.02 due to missing or incorrect nonce validation on the 'abundatrade' page. Nonces are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. The absence or improper implementation of nonce validation allows an attacker to craft a malicious request that, if executed by an authenticated site administrator (e.g., by clicking a link), can update plugin settings or inject malicious web scripts. This can lead to unauthorized changes in the plugin’s configuration and potential cross-site scripting (XSS) attacks, compromising the integrity and confidentiality of the affected site. The vulnerability requires user interaction (the administrator must be tricked into clicking a link) but does not require prior authentication by the attacker. The CVSS 3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and partial impact on confidentiality and integrity but no impact on availability. No known exploits are reported in the wild as of the published date (May 3, 2025). The vulnerability is classified under CWE-352, which specifically relates to CSRF attacks that exploit missing or incorrect anti-CSRF tokens.

For European organizations using WordPress sites with the Abundatrade Plugin installed, this vulnerability poses a moderate risk. Successful exploitation could allow attackers to alter plugin settings or inject malicious scripts, potentially leading to unauthorized data exposure, defacement, or further compromise of the website and its users. This could damage organizational reputation, lead to data breaches involving personal or sensitive customer data, and disrupt business operations reliant on the affected web services. Since many European companies rely on WordPress for their web presence, especially small and medium enterprises, the risk is non-negligible. The requirement for user interaction and targeting site administrators somewhat limits the attack surface but does not eliminate it, especially in environments where phishing or social engineering is prevalent. Additionally, the scope of impact could extend to GDPR compliance issues if personal data is exposed or manipulated, resulting in regulatory penalties and legal consequences.

1. Immediate patching or upgrading to a fixed version of the Abundatrade Plugin once released by withinboredom is the most effective mitigation. 2. Until a patch is available, implement web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the 'abundatrade' page. 3. Educate site administrators on the risks of clicking unsolicited links, especially those that could trigger administrative actions. 4. Employ additional security controls such as Content Security Policy (CSP) to mitigate the impact of any injected scripts. 5. Review and restrict administrative access to the WordPress backend to trusted personnel only, and enforce multi-factor authentication (MFA) to reduce the risk of compromised credentials. 6. Regularly audit plugin configurations and monitor logs for unusual changes or access patterns. 7. Consider isolating critical WordPress administrative interfaces behind VPNs or IP allowlists to reduce exposure.
