CVE-2026-33762
Impact
go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing.This issue only affects Git index format version 4. Earlier formats (
go-gitsupports onlyv2andv3) are not vulnerable to this issue.An attacker able to supply a crafted
.git/indexfile can cause applications using go-git to panic while reading the index. If the application does not recover from panics, this results in process termination, leading to a denial-of-service (DoS) condition.Exploitation requires the ability to modify or inject a Git index file within the local repository in disk. This typically implies write access to the
.gitdirectory.Patches
Users should upgrade to
v5.17.1, or the latestv6pseudo-version, in order to mitigate this vulnerability.Credit

Impact
A vulnerability has been identified in which a maliciously crafted
.idxfile can cause asymmetric memory consumption, potentially exhausting available memory and resulting in a Denial of Service (DoS) condition.Exploitation requires write access to the local repository's
.gitdirectory, it order to create or alter existing.idxfiles.Patches
Users should upgrade to
v5.17.1, or the latestv6pseudo-version, in order to mitigate this vulnerability.Credit
