CVE-2026-26307Network attack vector

Service exhaustion via unbounded git grep searches

Published Jul 3, 2026 · Updated Jul 3, 2026

Resource exhaustion in Gitea before 1.25.5 allows remote attackers to interrupt service through expensive repository searches. GrepSearch launches git grep without a command timeout, so attacker-controlled search patterns can keep consuming CPU and other server resources until the process finishes. The network-accessible repository search path requires no privileges or user interaction, and repeated costly searches can exhaust service capacity without affecting stored data.
