BREW-OPENTIMESTAMPS-CLIE… (GHSA-6P8H-3WGX-97GF)
Vulnerability from osv_homebrew – Published: 2026-08-14 09:30 – Updated: 2026-09-17 18:03 – Source websiteSummary
GitPython's unsafe_git_clone_options denylist omits --template. git clone --template=<dir> copies <dir>/hooks/ into the new repository and runs them (post-checkout fires during clone), so a caller who can influence clone options can achieve arbitrary command execution in the default allow_unsafe_options=False configuration.
Root Cause
base.py:145-152 defines unsafe_git_clone_options = ["--upload-pack","-u","--config","-c"] — --template is absent. The guard candidate ['--template'] passes check_unsafe_options (verified). git copies the hook directory and executes post-checkout at checkout time. git's protocol.allow/GIT_ALLOW_PROTOCOL do not gate --template; the incomplete denylist is the only defense.
Impact
Arbitrary OS command execution during clone (default config). Requires an attacker-readable directory containing an executable hook — a genuine second precondition (realistic via shared filesystems, upload dirs, /tmp, or attacker-writable network paths), reflected as AC:H.
Proof of Concept
# attacker stages <dir>/hooks/post-checkout (chmod +x)
from git import Repo
Repo.clone_from(src, dst, template='<dir>') # post-checkout hook executes -> marker created (verified)
Attack Chain
- Setup: attacker stages
<dir>/hooks/post-checkout(chmod +x). Guard: n/a (filesystem). - Entry:
Repo.clone_from(url, path, template='<dir>'). Guard:check_unsafe_options(candidates=['--template'], unsafe=unsafe_git_clone_options). Bypass proof:--templatenot on the denylist -> passes (verified candidate['--template'], no error). - Sink: git copies the hook and executes
post-checkoutat checkout. Impact: ACE, default config (verified marker created).
Bypass Evidence
Live-verified on HEAD (tag 3.1.53): guard candidate ['--template'] passed with no error; staged post-checkout hook executed during clone_from, creating the marker. Independent of the value-smuggle bypass (--template is a legitimate long option that survives any single-char-value fix). Not covered by any existing advisory.
Affected Versions
<= 3.1.53
Suggested Fix
Add --template (and audit for other hook/exec-influencing options) to unsafe_git_clone_options.

BREW-SHALLOW-BACKUP-CVE-… (GHSA-6P8H-3WGX-97GF)
Vulnerability from osv_homebrew – Published: 2026-08-14 09:39 – Updated: 2026-09-17 17:55 – Source websiteSummary
GitPython's unsafe_git_clone_options denylist omits --template. git clone --template=<dir> copies <dir>/hooks/ into the new repository and runs them (post-checkout fires during clone), so a caller who can influence clone options can achieve arbitrary command execution in the default allow_unsafe_options=False configuration.
Root Cause
base.py:145-152 defines unsafe_git_clone_options = ["--upload-pack","-u","--config","-c"] — --template is absent. The guard candidate ['--template'] passes check_unsafe_options (verified). git copies the hook directory and executes post-checkout at checkout time. git's protocol.allow/GIT_ALLOW_PROTOCOL do not gate --template; the incomplete denylist is the only defense.
Impact
Arbitrary OS command execution during clone (default config). Requires an attacker-readable directory containing an executable hook — a genuine second precondition (realistic via shared filesystems, upload dirs, /tmp, or attacker-writable network paths), reflected as AC:H.
Proof of Concept
# attacker stages <dir>/hooks/post-checkout (chmod +x)
from git import Repo
Repo.clone_from(src, dst, template='<dir>') # post-checkout hook executes -> marker created (verified)
Attack Chain
- Setup: attacker stages
<dir>/hooks/post-checkout(chmod +x). Guard: n/a (filesystem). - Entry:
Repo.clone_from(url, path, template='<dir>'). Guard:check_unsafe_options(candidates=['--template'], unsafe=unsafe_git_clone_options). Bypass proof:--templatenot on the denylist -> passes (verified candidate['--template'], no error). - Sink: git copies the hook and executes
post-checkoutat checkout. Impact: ACE, default config (verified marker created).
Bypass Evidence
Live-verified on HEAD (tag 3.1.53): guard candidate ['--template'] passed with no error; staged post-checkout hook executed during clone_from, creating the marker. Independent of the value-smuggle bypass (--template is a legitimate long option that survives any single-char-value fix). Not covered by any existing advisory.
Affected Versions
<= 3.1.53
Suggested Fix
Add --template (and audit for other hook/exec-influencing options) to unsafe_git_clone_options.

Suggested Fix
Add --template (and audit for other hook/exec-influencing options) to unsafe_git_clone_options.

BREW-TACH-CVE-2026-73623 (GHSA-6P8H-3WGX-97GF)
Vulnerability from osv_homebrew – Published: 2026-08-14 09:45 – Updated: 2026-09-17 18:35 – Source websiteSummary
GitPython's unsafe_git_clone_options denylist omits --template. git clone --template=<dir> copies <dir>/hooks/ into the new repository and runs them (post-checkout fires during clone), so a caller who can influence clone options can achieve arbitrary command execution in the default allow_unsafe_options=False configuration.
Root Cause
base.py:145-152 defines unsafe_git_clone_options = ["--upload-pack","-u","--config","-c"] — --template is absent. The guard candidate ['--template'] passes check_unsafe_options (verified). git copies the hook directory and executes post-checkout at checkout time. git's protocol.allow/GIT_ALLOW_PROTOCOL do not gate --template; the incomplete denylist is the only defense.
Impact
Arbitrary OS command execution during clone (default config). Requires an attacker-readable directory containing an executable hook — a genuine second precondition (realistic via shared filesystems, upload dirs, /tmp, or attacker-writable network paths), reflected as AC:H.
Proof of Concept
# attacker stages <dir>/hooks/post-checkout (chmod +x)
from git import Repo
Repo.clone_from(src, dst, template='<dir>') # post-checkout hook executes -> marker created (verified)
Attack Chain
- Setup: attacker stages
<dir>/hooks/post-checkout(chmod +x). Guard: n/a (filesystem). - Entry:
Repo.clone_from(url, path, template='<dir>'). Guard:check_unsafe_options(candidates=['--template'], unsafe=unsafe_git_clone_options). Bypass proof:--templatenot on the denylist -> passes (verified candidate['--template'], no error). - Sink: git copies the hook and executes
post-checkoutat checkout. Impact: ACE, default config (verified marker created).
Bypass Evidence
Live-verified on HEAD (tag 3.1.53): guard candidate ['--template'] passed with no error; staged post-checkout hook executed during clone_from, creating the marker. Independent of the value-smuggle bypass (--template is a legitimate long option that survives any single-char-value fix). Not covered by any existing advisory.
Affected Versions
<= 3.1.53
Suggested Fix
Add --template (and audit for other hook/exec-influencing options) to unsafe_git_clone_options.

Guard: `check_unsafe_options(candidates=[\u0027--template\u0027], unsafe=unsafe_git_clone_options)`. Bypass proof: `--template` not on the denylist -\u003e passes (verified candidate `[\u0027--template\u0027]`, no error).\n3. Sink: git copies the hook and executes `post-checkout` at checkout. Impact: ACE, default config (verified marker created).\n\n## Bypass Evidence\nLive-verified on HEAD (tag 3.1.53): guard candidate `[\u0027--template\u0027]` passed with no error; staged `post-checkout` hook executed during `clone_from`, creating the marker. Independent of the value-smuggle bypass (`--template` is a legitimate long option that survives any single-char-value fix). Not covered by any existing advisory.\n\n## Affected Versions\n`\u003c= 3.1.53`\n\n## Suggested Fix\nAdd `--template` (and audit for other hook/exec-influencing options) to `unsafe_git_clone_options`.\n\n---\nReported by **zx (Jace)** \u2014 GitHub: @manus-use",
