CVE-2024-10481 identifies a CSRF vulnerability in the comfyanonymous/comfyui project, specifically in versions up to v0.2.2. The vulnerability arises because critical API endpoints such as /upload/image, /prompt, and /history do not implement CSRF protections, allowing attackers to craft malicious websites that, when visited by authenticated users, cause the browser to send unauthorized API requests on the user's behalf. This can lead to unauthorized actions including uploading arbitrary files, which could be leveraged to introduce malicious content or manipulate application state. The absence of CSRF tokens or other anti-CSRF mechanisms on these endpoints is the root cause. Furthermore, this vulnerability can be chained with other weaknesses like stored cross-site scripting (XSS) to hijack user sessions or escalate privileges. The CVSS 3.0 score of 6.5 reflects that the attack vector is network-based, requires no privileges, but does require user interaction (visiting a malicious site). The impact is primarily on integrity, as attackers can modify or inject data via the API. No patches are currently linked, and no known exploits have been reported in the wild, indicating that organizations should proactively address this issue before exploitation occurs.

For European organizations using ComfyUI, this vulnerability poses a significant risk to the integrity of their systems and data. Attackers can exploit CSRF to perform unauthorized actions such as uploading arbitrary files, potentially leading to malware introduction, data manipulation, or disruption of workflows. If combined with stored XSS vulnerabilities, attackers could escalate the attack to session hijacking or persistent compromise. This is particularly concerning for organizations relying on ComfyUI for sensitive or critical operations, as unauthorized API requests could undermine trust in the system and lead to data breaches or operational disruptions. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit. Given the collaborative and often web-accessible nature of UI tools like ComfyUI, the threat surface is broad, and the impact could extend to multiple departments or users within an organization.

European organizations should immediately assess their use of ComfyUI and determine if they are running vulnerable versions (up to v0.2.2). Since no official patches are currently linked, organizations should implement the following mitigations: 1) Restrict access to the ComfyUI interface to trusted networks or VPNs to reduce exposure to malicious websites. 2) Employ web application firewalls (WAFs) to detect and block suspicious API requests that do not originate from legitimate user actions. 3) Educate users about the risks of visiting untrusted websites while authenticated to ComfyUI. 4) If possible, implement custom CSRF protections such as validating origin or referer headers on API endpoints. 5) Monitor logs for unusual API activity, especially on /upload/image, /prompt, and /history endpoints. 6) Consider isolating ComfyUI usage to dedicated environments with minimal sensitive data. 7) Stay updated with the vendor or community for forthcoming patches and apply them promptly once available.
