Name of the Vulnerable Software and Affected Versions
Directus versions prior to 11.16.0
Description
A Server-Side Request Forgery (SSRF) protection bypass exists in Directus. The IP address validation used to block requests to local and private networks could be circumvented using IPv4-Mapped IPv6 address notation. The validation logic failed to normalize IPv4-Mapped IPv6 addresses before checking them against the deny-list, allowing an attacker to bypass the restriction. This could allow an authenticated user (or an unauthenticated user if public file-import permissions are enabled) to perform SSRF attacks against internal services or cloud instance metadata endpoints.
Recommendations
Update to version 11.16.0 or later.
