Overview
Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information via improper validation of HTTP Vary header in SoupCache caching mechanism. An attacker can access confidential information by retrieving cached HTTP responses intended for other users.
Note:
This is only relevant to applications that explicitly enable SoupCache, and exploitation is more plausible in proxy-like scenarios rather than standard GNOME desktop use cases.
