CVE-2026-68520: Glances: as_dict_secure() Value-Level Bypass Leaks Credentials in URL Values via /api/4/config

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.40% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: nicolargo glances 4.5.6.

Low priority for now. Upgrade to nicolargo glances 4.5.6 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.6, as_dict_secure() in glances/config.py checks only option names and exposes public_username and credentials embedded in public_api values through unauthenticated GET /api/4/config and GET /api/4/config/ip requests. This issue is fixed in 4.5.6.
