CVE-2025-67622 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Evergreen Post Tweeter plugin developed by titopandub, which is used to automate posting evergreen content on social media platforms. The vulnerability affects all versions up to and including 1.8.9. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted requests to a web application, leveraging the victim's credentials and session. In this case, the CSRF flaw enables an attacker to inject malicious requests that result in Stored Cross-Site Scripting (XSS) payloads being saved within the application. Stored XSS can lead to persistent execution of malicious scripts in the context of other users, potentially stealing cookies, session tokens, or performing actions on behalf of users. The vulnerability does not require user interaction beyond visiting a crafted malicious webpage, making exploitation relatively straightforward. No CVSS score has been assigned yet, and no public exploits are known at this time. The vulnerability was published on December 24, 2025, and was reserved earlier that month. The lack of patches currently necessitates proactive defensive measures. The plugin is commonly used in WordPress environments, which are prevalent across many European organizations for content management and social media integration.

For European organizations, this vulnerability poses significant risks to web application security, particularly those relying on the Evergreen Post Tweeter plugin for social media automation. Successful exploitation could lead to unauthorized actions performed under legitimate user sessions, compromising data integrity and user trust. The Stored XSS aspect can facilitate persistent attacks, enabling attackers to steal sensitive information such as authentication tokens or manipulate user interactions. This can result in reputational damage, data breaches, and potential regulatory non-compliance under GDPR if personal data is exposed. Organizations with public-facing websites or intranets using this plugin are at risk of widespread impact, especially if administrative users are targeted. The ease of exploitation without requiring complex user interaction increases the threat level. Additionally, the absence of a patch at the time of disclosure means organizations must rely on mitigations to reduce exposure. The impact extends to operational disruption if attackers leverage the vulnerability to deface sites or propagate malware.

1. Immediately audit all WordPress installations to identify the presence of the Evergreen Post Tweeter plugin and its version. 2. Until an official patch is released, implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns targeting the plugin’s endpoints. 3. Enforce strict Content Security Policy (CSP) headers to mitigate the impact of Stored XSS by restricting script execution sources. 4. Review and harden user permissions to minimize the number of users with privileges to perform actions via the plugin. 5. Educate users and administrators about the risks of clicking on untrusted links, as CSRF attacks often rely on social engineering. 6. Monitor web server and application logs for unusual POST requests or suspicious activity related to the plugin. 7. Once patches become available, prioritize immediate testing and deployment in all affected environments. 8. Consider disabling or removing the plugin if it is not essential to reduce attack surface. 9. Implement anti-CSRF tokens and input validation in custom integrations if applicable. 10. Regularly update all WordPress plugins and core software to minimize exposure to known vulnerabilities.
