BREW-aider-CVE-2026-76221 — GitPython: git-config OPTION-name injection via =/#/whitespace bypasses name validator, enabling forged core.sshCommand…

Affected: Homebrew: aider

## Summary GitPython's config-name validator only neutralizes CR/LF/NUL for the `"option"` label; it does not reject `=`, `#`, `;`, `[`, `]`, or whitespace in an **option name**. `write_section` writes the option name verbatim into the config file, so an option name such as `sshCommand = touch <cmd> #` is written as `\tsshCommand = touch <cmd> # = <value>`, which git parses as `core.sshCommand = touch <cmd>` (the trailing `#` comments out the intended value). This forges arbitrary config directives (`core.sshCommand`, `core.hooksPath`, `alias.*`) → RCE on the next git operation. This is a distinct field (option name, not section name) and distinct character class (`=`/`#`/space, not newline/bracket) from GHSA-3rp5-jjmw-4wv2 (section-name bracket injection) and GHSA-mv93-w799-cj2w / GHSA-v87r-6q3f-2j67 (newline injection).

## Root Cause `_assure_config_name_safe(name, label)` (`git/config.py:897`) applies the bracket/quote state machine ONLY when `label == "section"`; for the `"option"` label it falls through with just the `UNSAFE_CONFIG_CHARS_RE = [\r\n\x00]` regex. `write_section` then writes the option name verbatim into `"\t%s = %s\n"` (config.py:702).

## Impact Arbitrary git-config directive injection → remote code execution via `core.sshCommand` (fires on any ssh git operation, no staged file needed) or `core.hooksPath` (with a staged hook). Requires the embedding application to forward a caller-influenced OPTION NAME into the config writer (name-control model, the sa…

GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshCommand = touch /tmp/RCE #' to execute arbitrary commands via core.sshCommand or core.hooksPath on the next git operation.

OESA-2026-3699 — python-GitPython security update

Affected: openEuler:24.03-LTS-SP1: python-GitPython

GitPython is a python library used to interact with git repositories, high-level like git-porcelain, or low-level like git-plumbing. Security Fix(es):

GitPython before 3.1.57 contains an incomplete denylist in the unsafe_git_archive_options guard that omits --add-file and --add-virtual-file options. Attackers can supply these options to Repo.archive() to read arbitrary files from the filesystem and include them in the returned archive.(CVE-2026-73619)

GitPython before 3.1.57 fails to guard git option forwarding in IndexFile.checkout() and TagReference.create(), allowing attackers to pass unsafe options via kwargs. Attackers can use --prefix to overwrite arbitrary files with repository content or -F to read arbitrary files returned in-band.(CVE-2026-73620)

GitPython before 3.1.56 contains an argument injection vulnerability in the Commit.count() method, which forwards keyword arguments to 'git rev-list' without the check_unsafe_options guard present in the sibling iter_items method. An attacker who can control options passed to Commit.count (e.g., via an application that forwards a user-supplied options dict) can supply output=<path>, causing 'git rev-list --output=<path>' to open and truncate the target file to zero bytes before revision parsing. This allows destruction/blanking of an arbitrary file at the process's privilege level (no content control, 0-byte truncation).(CVE-2026-73621)
