Vulnerability Title
Quay: repository auto-prune policy uuid idor in quay api

Vulnerability Description
A flaw was found in Quay. An authenticated attacker can access repository auto-prune configurations from other namespaces, leading to unauthorized information disclosure. This issue occurs because the application does not properly enforce namespace scoping when retrieving policy details by repository name and policy identifier. To exploit the vulnerability, the attacker must manage a repository sharing the target's name and know the target policy's unique identifier.
