CVE-2026-68517Public exploitNetwork attack vector

Cross-origin data disclosure via credentialed wildcard CORS

Published Aug 17, 2026 · Updated Aug 18, 2026

Permissive CORS in Nicolargo Glances before 4.5.6 allows remote attackers to read authenticated REST API data through a victim's browser. The REST API guard in glances/outputs/glances_restful_api.py compares cors_origins with a single-item wildcard list, so a multi-origin list containing the wildcard leaves credentialed origin reflection enabled. Exploitation requires cors_credentials enabled, a wildcard-bearing multi-origin list, and a visitor with cached HTTP Basic credentials; exposed data includes process command lines and usernames.
