Vulnerability Description
MISP has a security issue that can let a user gain more access than their API key is supposed to allow. A read-only API key should only let someone view information. However, after logging in with such a key, a specific MISP function could accidentally restore the user’s normal account permissions. This means someone with a read-only API key could potentially gain write, delete, or even administrator access if their underlying account has those permissions. Exploiting the issue requires a valid read-only API key and a single request to the affected function. The main impact is that MISP’s API key restrictions can be bypassed, allowing actions that the API key was specifically meant to prevent. Version affected: <2.5.47
