libgit2: Submodule path traversal
CVE-2026-53584 is fixed in 36 products on 1 platform, first by libgit2-1.9 1.9.1+ds-1ubuntu1.1, released July 30, 2026. It is not reported as exploited. Patch Radar priority: Routine.
libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, libgit2 does not reject traversal components in a submodule path loaded from .gitmodules. The affected src/libgit2/submodule.c paths include git_submodule_lookup and git_submodule_add_setup. A crafted repository can specify a path such as ../escape-target, and applications that initialize the submodule can create directories outside the repository working tree. This issue is fixed in versions 1.8.6 and 1.9.5.
