Glances: REST API CORS Credentials Guard Uses Exact-Match Instead of Membership Test — Bypassed by Any Multi-Origin Allowlist Containing the Wildcard

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, the cors_origins guard in glances/outputs/glances_restful_api.py uses exact list equality instead of wildcard membership, allowing a multi-origin list containing the wildcard to retain cors_credentials and expose authenticated REST API data to an untrusted website visited by a previously authenticated user. This issue is fixed in 4.5.6.
