CVE-2025-22590 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the mmrs151 Prayer Times Anywhere application, specifically affecting versions up to and including 2.0.1. The vulnerability allows attackers to trick authenticated users into submitting unauthorized requests to the application, which can result in Stored Cross-Site Scripting (XSS). Stored XSS occurs when malicious scripts are permanently stored on the target server, such as in a database, and then executed in the browsers of users who access the affected content. This combination of CSRF and Stored XSS is particularly dangerous because CSRF can be used to inject malicious payloads without the user's consent, and Stored XSS can lead to persistent compromise of user sessions, theft of cookies, credentials, or other sensitive information, and potentially facilitate further attacks such as privilege escalation or spreading malware. The vulnerability affects the Prayer Times Anywhere product, which is used to provide Islamic prayer times, and is likely deployed in environments serving Muslim communities. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed or scored by standard frameworks, and no patches or exploits have been publicly disclosed at the time of publication. The vulnerability was published on January 7, 2025, by Patchstack, with no known exploits in the wild. The absence of patch links suggests that users must implement interim mitigations until an official fix is released.

The impact of CVE-2025-22590 is significant for organizations using Prayer Times Anywhere, especially those serving large Muslim populations or managing prayer schedules in institutional or community settings. Exploitation can lead to unauthorized actions performed on behalf of authenticated users, compromising the integrity of user data and application functionality. Stored XSS can result in persistent malicious code execution, enabling attackers to steal session tokens, hijack accounts, manipulate displayed content, or deliver malware. This can undermine user trust, cause data breaches, and disrupt service availability. Organizations may face reputational damage, regulatory consequences if personal data is compromised, and operational disruptions. Since the vulnerability requires an authenticated user session, attackers may need to target users with valid credentials, but social engineering or phishing could facilitate this. The lack of known exploits currently reduces immediate risk, but the presence of a stored XSS payload increases the potential for widespread impact once exploited.

To mitigate CVE-2025-22590, organizations should implement multiple layers of defense. First, apply strict anti-CSRF tokens on all state-changing requests to ensure that requests originate from legitimate users and sessions. Validate the origin and referer headers where applicable. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS. Sanitize and validate all user inputs rigorously to prevent injection of malicious scripts into stored data. Limit user privileges to the minimum necessary to reduce the scope of potential damage. Monitor application logs for unusual activities indicative of CSRF or XSS attempts. Educate users about phishing and social engineering risks that could lead to session hijacking. Until an official patch is released, consider isolating the application or restricting access to trusted networks. Regularly check for vendor updates or patches and apply them promptly once available.
