GHSA-R9MR-M37C-5FR3 GitPython: Unsafe git option guard bypass via single-character kwarg value token smuggling enables arbitrary command execution

Summary GitPython's checkunsafeoptions guard the control introduced by CVE-2026-42215 / GHSA-2f96 and hardened since can be bypassed for every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by smuggling an option token inside the VALUE of a single-character...

golang: github.com/go-git/go-git: go-git: Information disclosure of HTTP authentication credentials via redirects

A flaw was found in go-git, an extensible Git implementation library for Go. This vulnerability allows an attacker to potentially obtain sensitive HTTP authentication credentials. This can occur when go-git follows redirects during smart-HTTP clone and fetch operations, leading to the unintended...

CVE-2026-42215

GitPython is a python library used to interact with Git repositories. From version 3.1.30 to before version 3.1.47, GitPython blocks dangerous Git options such as --upload-pack and --receive-pack by default, but the equivalent Python kwargs uploadpack and receivepack bypass that check. If an...

gix-pack has multiple DoS vectors: unchecked indexing panics and uncapped OOM allocations from crafted pack data

Summary Multiple denial-of-service vectors in gix-pack: unchecked array indexing causes panics on crafted delta data, and uncapped attacker-controlled size headers enable OOM process kills. Both are triggered by malicious pack data received during clone/fetch. Details Bug 1: Unchecked array...
