Name of the Vulnerable Software and Affected Versions LinkAce versions prior to 2.5.3

Description LinkAce is a self-hosted archive for collecting website links. Versions before 2.5.3 prevent direct requests to private IP literals, but continue to make server-side requests to internal resources when referenced via an internal hostname. This allows an authenticated user to initiate server-side requests to internal services accessible by the LinkAce server, but not directly accessible from outside the network. The issue involves server-side request forgery, where an attacker can leverage the server to access internal resources.

Recommendations Update to version 2.5.3 or later.
