CVE-2026-78676
Last modified
CVE-2026-78676 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. GitPython before 3.1.59 fails to safely re-serialize multi-line git-config values during write operations, corrupting dormant quoted values into injected directives like core.hooksPath. Attackers can craft config files with embedded newlines that become live git directives after any unrelated GitPython config write, enabling arbitrary code execution via hook invocation.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
