CVE-2025-49343 identifies a Cross-Site Request Forgery (CSRF) vulnerability in Socialprofilr's Social Profilr software, versions up to 1.0. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unintended requests to a web application, exploiting the user's active session. In this case, the CSRF flaw facilitates stored Cross-Site Scripting (XSS) attacks, where malicious scripts injected by the attacker are permanently stored on the target server and executed in the context of other users' browsers. The vulnerability does not require prior authentication (PR:N) but does require user interaction (UI:R), such as clicking a crafted link or visiting a malicious webpage. The CVSS 3.1 score of 7.1 reflects a high severity, with network attack vector (AV:N), low attack complexity (AC:L), and a scope change (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability at a low to moderate level (C:L/I:L/A:L). No patches or public exploits are currently available, but the vulnerability is published and recognized by Patchstack. The lack of patches means organizations must rely on mitigation strategies until a fix is released.

For European organizations, this vulnerability poses a significant risk, especially those using Social Profilr for managing social profiles or user-generated content. Successful exploitation can lead to unauthorized actions performed on behalf of users, including injecting malicious scripts that can steal sensitive information, manipulate data, or disrupt service availability. This can result in data breaches, reputational damage, and compliance violations under regulations such as GDPR. The stored XSS aspect increases risk by enabling persistent attacks affecting multiple users. The vulnerability's network accessibility and lack of required authentication make it easier for attackers to exploit, increasing the threat surface. Organizations with public-facing social profile management systems or those integrating Social Profilr into their web infrastructure are particularly vulnerable.

1. Implement anti-CSRF tokens in all state-changing requests to ensure that requests originate from legitimate users. 2. Validate the Origin and Referer headers on the server side to confirm requests come from trusted sources. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and mitigate XSS impact. 4. Conduct thorough input validation and output encoding to prevent injection of malicious scripts. 5. Monitor web application logs for unusual or unauthorized requests indicative of CSRF or XSS attempts. 6. Educate users about the risks of clicking untrusted links and encourage cautious browsing behavior. 7. Apply network-level protections such as Web Application Firewalls (WAFs) configured to detect and block CSRF and XSS attack patterns. 8. Stay updated with vendor advisories and apply patches promptly once available. 9. Consider isolating or limiting the use of Social Profilr in critical environments until a patch is released.
