Summary

GitPython: Incomplete unsafe_git_revision_options denylist omits --contents/-S, enabling arbitrary file read via Repo.blame()

Details

Summary

Repo.blame() / Repo.blame_incremental() guard forwarded revision options against unsafe_git_revision_options, but that denylist only contains the file-WRITE options --output/-o. git blame also honors --contents <file> and -S <file>, which cause the file's lines to be echoed into the blame result — an arbitrary file READ. Neither option is in the denylist, so a caller-influenced revision value of --contents=<path> passes the guard and leaks file contents. This is a distinct sink-option and impact class (READ) from GHSA-956x-8gvw-wg5v (which addressed the blame --output WRITE), directly analogous to GHSA-539m-9xh6-q6rr (archive READ gap accepted separately from the archive write/exec advisory).

Root Cause

unsafe_git_revision_options = ["--output","-o"] (git/repo/base.py:188). The rev string is passed to _option_candidates([rev], kwargs) and placed BEFORE the -- separator (base.py:841). The canonical name of --contents=... is contents, which is not on the denylist, so no UnsafeOptionError is raised. The trailing -- protects only the pathspec, not the option before the revision.

Impact

Arbitrary local file read at the privileges of the host process; the file's line contents appear in the blame result returned to the caller. Pure VALUE control (the caller forwards a user-influenced revision string). Default allow_unsafe_options=False.

Proof of Concept

result = repo.blame("--contents=/etc/passwd", "a.txt")
# result rows carry the victim file's line text

Attack Chain

Entry: app calls repo.blame(rev, file) with attacker rev="--contents=/etc/passwd" (or kwarg contents="/etc/passwd", or -S).
Check: Git.check_unsafe_options(_option_candidates([rev,...], kwargs), unsafe_git_revision_options) @ base.py:841. Guard: denylist = ["--output","-o"] only. Bypass proof: canonical name contents ∉ denylist → no error.
Sink: self.git.blame(rev, "--", file, p=True, ...). argv (observed): ['git','blame','-p','--contents=<secret>','HEAD','--','a.txt'].
Impact: blame result rows carry the victim file's line text.

Bypass Evidence

Independently reproduced (independent test harness, default allow_unsafe_options=False): blame('--contents=<secret>','a.txt') → guard PASSED; result rows = ['GATE_SECRET_LINE_A','GATE_SECRET_LINE_B']. Control: blame('--output=…') still BLOCKED (guard active on this path). -S kwarg argv also reaches git unguarded.

Affected Versions

GitPython <= 3.1.58 (denylist present verbatim on the latest release tag).

Suggested Fix

Prefer an allowlist of blame options; at minimum add --contents/-S (and any other path-taking blame options) to unsafe_git_revision_options, and make the membership rule "the option takes a filesystem path" rather than "the option writes output".

CVE-2026-78678 (GCVE-0-2026-78678)

Vulnerability from cvelistv5 – Published: 2026-08-25 01:30 – Updated: 2026-08-25 15:18

Title

GitPython before 3.1.59 Arbitrary File Read via Repo.blame()

Summary

GitPython versions before 3.1.59 contain an incomplete denylist in the unsafe_git_revision_options guard that omits --contents and -S options, allowing attackers to read arbitrary files by passing these options to Repo.blame(). Attackers can supply revision values like --contents=/etc/passwd to leak file contents through the blame result returned to the caller.

Summary

GitPython: Incomplete unsafe_git_revision_options denylist omits --contents/-S, enabling arbitrary file read via Repo.blame()

Details

Summary

Root Cause

Impact

Proof of Concept

result = repo.blame("--contents=/etc/passwd", "a.txt")
# result rows carry the victim file's line text

Attack Chain

Entry: app calls repo.blame(rev, file) with attacker rev="--contents=/etc/passwd" (or kwarg contents="/etc/passwd", or -S).
Check: Git.check_unsafe_options(_option_candidates([rev,...], kwargs), unsafe_git_revision_options) @ base.py:841. Guard: denylist = ["--output","-o"] only. Bypass proof: canonical name contents ∉ denylist → no error.
Sink: self.git.blame(rev, "--", file, p=True, ...). argv (observed): ['git','blame','-p','--contents=<secret>','HEAD','--','a.txt'].
Impact: blame result rows carry the victim file's line text.

Bypass Evidence

Affected Versions

GitPython <= 3.1.58 (denylist present verbatim on the latest release tag).

  "details": "## Summary\n`Repo.blame()` / `Repo.blame_incremental()` guard forwarded revision options against `unsafe_git_revision_options`, but that denylist only contains the file-WRITE options `--output`/`-o`. `git blame` also honors `--contents \u003cfile\u003e` and `-S \u003cfile\u003e`, which cause the file\u0027s lines to be echoed into the blame result \u2014 an arbitrary file READ. Neither option is in the denylist, so a caller-influenced revision value of `--contents=\u003cpath\u003e` passes the guard and leaks file contents. This is a distinct sink-option and impact class (READ) from GHSA-956x-8gvw-wg5v (which addressed the blame `--output` WRITE), directly analogous to GHSA-539m-9xh6-q6rr (archive READ gap accepted separately from the archive write/exec advisory).\n\n## Root Cause\n`unsafe_git_revision_options = [\"--output\",\"-o\"]` (`git/repo/base.py:188`). The `rev` string is passed to `_option_candidates([rev], kwargs)` and placed BEFORE the `--` separator (base.py:841). The canonical name of `--contents=...` is `contents`, which is not on the denylist, so no `UnsafeOptionError` is raised. The trailing `--` protects only the pathspec, not the option before the revision.\n\n## Impact\nArbitrary local file read at the privileges of the host process; the file\u0027s line contents appear in the blame result returned to the caller. Pure VALUE control (the caller forwards a user-influenced revision string). Default `allow_unsafe_options=False`.\n\n## Proof of Concept\n```python\nresult = repo.blame(\"--contents=/etc/passwd\", \"a.txt\")\n# result rows carry the victim file\u0027s line text\n```\n\n## Attack Chain\n1. Entry: app calls `repo.blame(rev, file)` with attacker `rev=\"--contents=/etc/passwd\"` (or kwarg `contents=\"/etc/passwd\"`, or `-S`).\n2. Check: `Git.check_unsafe_options(_option_candidates([rev,...], kwargs), unsafe_git_revision_options)` @ base.py:841. Guard: denylist = `[\"--output\",\"-o\"]` only. Bypass proof: canonical name `contents` \u2209 denylist \u2192 no error.\n3. Sink: `self.git.blame(rev, \"--\", file, p=True, ...)`. argv (observed): `[\u0027git\u0027,\u0027blame\u0027,\u0027-p\u0027,\u0027--contents=\u003csecret\u003e\u0027,\u0027HEAD\u0027,\u0027--\u0027,\u0027a.txt\u0027]`.\n4. Impact: blame result rows carry the victim file\u0027s line text.\n\n## Bypass Evidence\nIndependently reproduced (independent test harness, default `allow_unsafe_options=False`): `blame(\u0027--contents=\u003csecret\u003e\u0027,\u0027a.txt\u0027)` \u2192 guard PASSED; result rows = `[\u0027GATE_SECRET_LINE_A\u0027,\u0027GATE_SECRET_LINE_B\u0027]`. Control: `blame(\u0027--output=\u2026\u0027)` still BLOCKED (guard active on this path). `-S` kwarg argv also reaches git unguarded.\n\n## Affected Versions\n`GitPython \u003c= 3.1.58` (denylist present verbatim on the latest release tag).\n\n## Suggested Fix\nPrefer an allowlist of blame options; at minimum add `--contents`/`-S` (and any other path-taking blame options) to `unsafe_git_revision_options`, and make the membership rule \"the option takes a filesystem path\" rather than \"the option writes output\".\n\n---\nReported by **zx (Jace)** \u2014 GitHub: @manus-use",
