CVE-2026-78676— GitPython before 3.1.59 Remote Code Execution via Config Injection

Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GitPython 在 3.1.59 版本之前，在写操作过程中无法安全地重新序列化多行的 git-config 值，会导致原本被引号包裹的静默配置值被损坏，并演变为类似 core.hooksPath 等可注入的指令。攻击者可以构造包含嵌入换行符的配置文件，这些文件在任意不相关的 GitPython 配置写操作后，会转化为实际生效的 Git 指令，从而通过钩子（hook）调用实现任意代码执行。

Vulnerability Title
GitPython before 3.1.59 Remote Code Execution via Config Injection
Source: CVE Program / CVE List V5
Vulnerability Description
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.
