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.
