CVE-2025-22747 identifies a stored cross-site scripting (XSS) vulnerability in the tormorten Foundation Columns product, specifically affecting versions up to and including 0.8. The root cause is improper neutralization of input during web page generation, which allows malicious input to be embedded and stored within the application’s content. When other users access the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, unauthorized actions, or distribution of malware. Stored XSS is particularly dangerous because the payload persists on the server and can impact multiple users without requiring repeated attacker interaction. The vulnerability does not require authentication, increasing the attack surface, and no user interaction beyond visiting the compromised page is needed to trigger the exploit. Although no public exploits have been reported yet, the vulnerability’s characteristics make it a critical concern for web applications relying on Foundation Columns for layout or content management. The absence of a CVSS score necessitates a severity assessment based on impact and exploitability factors.

The impact of CVE-2025-22747 is significant for organizations using Foundation Columns in their web applications. Successful exploitation can lead to theft of sensitive user data such as session cookies, personal information, or authentication tokens, enabling attackers to impersonate users or escalate privileges. It can also facilitate the injection of malicious scripts that perform unauthorized actions on behalf of users, deface websites, or spread malware. This undermines user trust, damages organizational reputation, and may lead to regulatory penalties if personal data is compromised. The persistent nature of stored XSS means multiple users can be affected over time, amplifying the damage. Additionally, attackers could leverage this vulnerability as a foothold for further attacks within the network. Organizations worldwide that rely on Foundation Columns for web content layout or management are at risk, especially those with public-facing web portals or high-value user bases.

To mitigate CVE-2025-22747, organizations should immediately upgrade Foundation Columns to a version where the vulnerability is patched once available. In the absence of an official patch, apply strict input validation and output encoding on all user-supplied data before rendering it in web pages. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regularly audit and sanitize stored content to remove any malicious payloads. Implement web application firewalls (WAFs) with rules designed to detect and block XSS attack patterns targeting this vulnerability. Educate developers on secure coding practices to prevent improper input neutralization. Monitor web application logs for unusual activity indicative of exploitation attempts. Finally, conduct penetration testing focused on XSS vulnerabilities to identify and remediate similar issues proactively.
