The vulnerability identified as CVE-2026-22359 is a Cross-Site Request Forgery (CSRF) flaw in the AA-Team Wordpress Movies Bulk Importer plugin, affecting versions up to 1.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unintended actions on behalf of the user. In this case, the vulnerability allows an attacker to induce an authenticated Wordpress administrator to perform bulk movie import operations without their knowledge or consent. This can lead to unauthorized content being added or manipulated within the Wordpress site. The plugin lacks adequate CSRF protections such as nonce tokens or proper request validation mechanisms. Although no public exploits or patches are currently available, the vulnerability is publicly disclosed and should be considered a risk for sites using this plugin. The attack requires the victim to be authenticated in Wordpress with sufficient privileges, but does not require additional user interaction beyond visiting a malicious page. This vulnerability primarily threatens the integrity of the Wordpress site and could be leveraged to inject unwanted content or disrupt site operations. The absence of a CVSS score necessitates an assessment based on impact and exploitability factors.

For European organizations, especially those relying on Wordpress for content management and using the AA-Team Movies Bulk Importer plugin, this vulnerability poses a significant risk to site integrity. Unauthorized bulk imports could lead to content pollution, misinformation, or defacement, damaging brand reputation and user trust. Media companies, entertainment portals, and cultural institutions that publish movie-related content are particularly vulnerable. The attack could also be a vector for further exploitation if malicious content includes scripts or links leading to malware or phishing. Since the vulnerability requires an authenticated administrator, organizations with weak access controls or shared admin credentials are at higher risk. The impact on availability is limited but could occur if the site becomes unstable due to malicious imports. Confidentiality is less directly affected unless combined with other vulnerabilities. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability is widely known.

To mitigate this vulnerability, organizations should first verify if they use the AA-Team Wordpress Movies Bulk Importer plugin and update or disable it if possible. Since no patch is currently available, administrators should implement manual CSRF protections by ensuring that all state-changing requests require nonce tokens or similar anti-CSRF mechanisms. Restrict plugin usage to the minimum number of trusted administrators and enforce strong authentication policies, including multi-factor authentication. Monitor Wordpress logs for unusual bulk import activities or unexpected POST requests to the plugin endpoints. Employ web application firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting Wordpress plugins. Regularly audit installed plugins for security issues and remove unused or unsupported plugins. Educate administrators about the risks of CSRF and the importance of not visiting untrusted websites while logged into Wordpress admin accounts. Finally, stay informed about vendor updates or patches addressing this vulnerability and apply them promptly when available.
