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...
