Routine

HIGH 8.4UPGRADE

CVE-2026-78675 is a high-severity flaw (CVSS 8.4) affecting gitpython. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

GitPython before 3.1.59 fails to disable merge_includes when parsing .gitmodules, allowing attackers to disclose local file content by including arbitrary file paths via [include] directives. Attackers can craft a malicious .gitmodules file with include directives pointing to sensitive files; when repo.submodules is accessed, GitConfigParser raises MissingSectionHeaderError embedding the target file's first line verbatim in the exception message.
