CVE-2026-12547 Libsoup: information disclosure in libsoup via soupauthmanager proxy credential leak on proxy switch
Description
SoupAuthManager caches proxy authentication credentials without scoping them to the proxy authority (host:port). When the proxy configuration changes (e.g., via system settings or WPAD), cached Proxy-Authorization headers from the previous proxy are sent to the new proxy, leaking credentials.
