CVE-2026-82289
Attackers can submit URLs with attacker-controlled hostnames to trigger outbound connections to arbitrary hosts and disclose GitHub personal access tokens via HTTP basic credentials.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Gitingest through 0.3.1 fails to properly validate hostnames in _validate_host, accepting any host with a git., gitlab., or github. prefix regardless of known-hosts list membership. Attackers can submit URLs with attacker-controlled hostnames to trigger outbound connections to arbitrary hosts and disclose GitHub personal access tokens via HTTP basic credentials.
