CVE-2025-59831Public exploitNetwork attack vector

Arbitrary command execution via revisionRange concatenation

Published Sep 25, 2025 · Updated Sep 25, 2025

Command injection in snowyu git-commiters before 0.1.2 allows remote attackers to execute arbitrary OS commands via a crafted revision range. The gitCommiters API concatenates revisionRange into a shell command without separating arguments, so shell metacharacters alter the command. Exploitation requires a consuming application to pass attacker-controlled revisionRange input to the library; commands run with that application's privileges.
