CVE-2026-94404MISP CSRF vulnerability allows unauthorized attribute modification
High 7.1
In plain English
A high-severity cross-site request forgery in MISP from MISP. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 12% of all known vulnerabilities).
Official description
MISP has a security issue that could let an attacker change threat-intelligence data through a logged-in user’s browser without that user knowingly approving the change. The affected function did not properly enforce MISP’s usual protection against forged requests. Because of this, an attacker could create a malicious webpage that silently sends a request to MISP when visited by an authenticated user. If successful, the attacker could change details of an attribute, such as its value, type, category, comment, distribution settings, or related timestamps. The attack requires the victim to already be logged in to MISP and to visit an attacker-controlled page. The main impact is unauthorized modification of threat-intelligence data, which could lead to incorrect indicators, wrong classifications, or altered sharing settings and reduce confidence in the accuracy of the information stored in MISP. Version affected: <2.5.47
