A vulnerability has been identified in Fleet when the webhook endpoint is configured without a secret; an attacker can forge webhook requests. The attacker doesn't need to know the specific repository or path configured in the GitRepo resource to make Fleet process these requests.
An attacker can exploit this vulnerability to cause the following impacts:
Please consult the associated MITRE ATT&CK - Technique - T1499.004: Endpoint Denial of Service for further information about this category of attack.
To resolve this vulnerability, upgrade Fleet to a patched version. This upgrade version escapes the URL and path to the remote repository received from webhooks, which prevents regular expressions from being used as a replacement for the URL and path.
Patched versions of Fleet include releases v0.15.2, v0.14.6, 0.13.11, and v0.12.15.
If you can't upgrade to a fixed version, please make sure to only enable webhooks with a shared secret.
