GHSA-J535-V25Q-VX3Q n8n: Regular Expression Denial of Service in the Default Blocked-File-Pattern Match via a Git Node Clone Path

Impact The Git node's clone operation matched the destination path against the default N8NBLOCKFILEPATTERNS expression, which was written so that a crafted path caused catastrophic backtracking. Evaluation runs synchronously in the main n8n process, so an authenticated user could freeze the...

github.com/go-git/go-git/v5: go-git: Arbitrary file read/write via symbolic link resolution

A flaw was found in go-git, an extensible Git implementation library. Worktree operations, such as checkout, status, and add, resolve symbolic links within the working tree without proper boundary confinement. This allows a remote attacker to craft a malicious repository containing a symlink,...

PYSEC-2026-3835 GitHacker: Path traversal in ref/hash parsing enables existence oracle and hex-fragment exfiltration via malicious .git server

Summary GitHacker through 1.1.7 did not validate path segments parsed from attacker-controlled .git/HEAD before joining them onto its output directory. A malicious server could coerce GitHacker into reading arbitrary local files. Contents do not stream back wholesale, but the recovery loop turns...

PYSEC-2026-3840 GitPython: Unguarded git option forwarding in Repo.init enables arbitrary command execution via --template clone hooks

Summary Repo.init forwards kwargs verbatim to git init with no unsafe-option guard and no allowunsafeoptions parameter. git init --template= copies /hooks/ into the new repo's .git/hooks, so an attacker-controlled template kwarg plants a hook that executes on the next git operation → arbitrary co...

SUSE CVE-2026-87817

GitPython before 3.1.60 fails to properly validate the git directory location, allowing attackers to impersonate the git directory using tracked files like gitdir, commondir, and HEAD. Attackers can execute arbitrary code by placing a malicious pre-commit hook in the tracked hooks directory that...
