📋 Description

Impact

The Instagram authentication adapter allows clients to specify a custom API URL via the apiURL parameter in authData. This enables SSRF attacks and possibly authentication bypass if malicious endpoints return fake responses to validate unauthorized users.

Patches

Fixed by hardcoding the Instagram Graph API URL https://graph.instagram.com and ignoring client-provided apiURL values.

Workarounds

None.
