CVE-2025-49964 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the indgeek ClipLink product, affecting versions up to 1.1. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application in which the user is currently authenticated. This can lead to unauthorized actions being performed on behalf of the user without their consent. In this case, the vulnerability allows attackers to craft malicious web requests that, when executed by a logged-in user, can cause unintended state-changing operations within the ClipLink application. The CVSS 3.1 base score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N), requires low attack complexity (AC:L), does not require privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L) with no impact on confidentiality or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-352, which highlights the lack of proper anti-CSRF protections such as tokens or same-site cookie attributes in the affected ClipLink versions. Given that ClipLink is a web-based product, this vulnerability could be exploited via social engineering or malicious websites to induce users to perform unintended actions within the ClipLink environment.

For European organizations using indgeek ClipLink, this vulnerability poses a risk primarily to the integrity of data or configurations managed through the application. Attackers could manipulate user actions to alter settings, upload or modify content, or perform other state-changing operations without authorization. Although confidentiality and availability are not directly impacted, the integrity compromise could lead to operational disruptions, data corruption, or unauthorized changes that affect business processes. Organizations in sectors with high reliance on web-based collaboration or content management tools may face increased risk. Since exploitation requires user interaction, phishing or social engineering campaigns could be leveraged to trigger the vulnerability. The absence of known exploits reduces immediate risk, but the lack of patches means the vulnerability remains open for future exploitation. European organizations with users who have authenticated sessions in ClipLink are vulnerable, especially if users access the application from browsers susceptible to CSRF attacks and if no compensating controls are in place.

1. Implement strict anti-CSRF protections: Developers and administrators should ensure that ClipLink includes CSRF tokens in all state-changing requests and validates them server-side. 2. Enforce SameSite cookie attributes (preferably 'Strict' or 'Lax') to limit cookie transmission in cross-site requests. 3. Educate users to avoid clicking on suspicious links or visiting untrusted websites while logged into ClipLink. 4. Use Content Security Policy (CSP) headers to restrict the domains from which scripts can be loaded, reducing the risk of malicious script execution. 5. Monitor user activity logs for unusual or unauthorized actions that could indicate exploitation attempts. 6. Network-level mitigations such as web application firewalls (WAFs) can be configured to detect and block suspicious cross-site requests targeting ClipLink endpoints. 7. Since no patch is currently available, organizations should consider isolating ClipLink access to trusted networks or VPNs to reduce exposure. 8. Regularly check for vendor updates or patches addressing this vulnerability and apply them promptly once released.
