CVE-2026-106059
HIGH 8.7GitAhead through 2.7.1 on macOS contains a command injection vulnerability that allows attackers to execute shell commands by crafting repository filenames interpolated unescaped into the Show in Finder AppleScript. Attackers can commit a file whose path contains a double quote followed by a do shell script payload, which runs as the victim user when Show in Finder is chosen.
Severe if exploited (CVSS 8.7), but no known exploitation and low modeled probability. Patch on a normal cadence.
