CVE-2025-48384: Git Submodule RCE Remediation

High CVSS 8 CISA KEV

Overview

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals. When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. This vulnerability is fixed in v2.43.7, v2.44.4, v2.45.4, v2.46.4, v2.47.3, v2.48.2, v2.49.1, and v2.50.1.

Detection and triage

Use read-only checks to decide whether CVE-2025-48384 reaches an owned asset. Treat advisories and proof-of-concept material as evidence, never as executable instructions.

Reviewed detection guidance

  • Dockerfiles, devcontainers, CI images, runner bootstrap scripts, package manager manifests, release images, or workstation setup docs install Git in an affected range.
  • CI or automation uses recursive submodules, for example git clone --recurse-submodules, git submodule update --init --recursive, or actions/checkout with submodules: recursive.
  • The repository imports, mirrors, scans, builds, lints, tests, or evaluates repositories that can be influenced by users, tenants, partners, bug-bounty reporters, dependency scanners, model/agent tasks, or external tickets.
  • Build or agent runtimes run Git with access to repository secrets, signing keys, package publishing tokens, cloud credentials, deployment credentials, SSH agents, source-code mirrors, or internal networks.
  • The repository has no policy or tests that distinguish trusted first-party submodules from untrusted repository intake.

Quick checks:

git --version
rg -n "recurse-submodules|submodule update|submodules:|actions/checkout|git clone|git fetch|git checkout|core\\.hooksPath|GIT_CONFIG|\\.gitmodules" .github Dockerfile* docker .devcontainer scripts Makefile . || true
find . -name .gitmodules -print

Windows:

git --version
rg -n "recurse-submodules|submodule update|submodules:|actions/checkout|git clone|git fetch|git checkout|core\.hooksPath|GIT_CONFIG|\.gitmodules" .github Dockerfile* docker .devcontainer scripts Makefile .
Get-ChildItem -Recurse -Force -Filter .gitmodules | Select-Object -ExpandProperty FullName

Do not validate exposure by cloning public proof-of-concept repositories, executing hooks, or running recursive checkout on attacker-controlled content.

Detection signals and verification

  • Archive extraction, Unicode normalization, encoded separators, Windows device names, network paths, and case-insensitive filesystems.
  • Symlink and time-of-check/time-of-use races between validation and file access.
  • File-type decisions based only on extension or caller-supplied content type.

Stop and triage

  • Stop if validation occurs only before a later path transformation or does not account for links and platform semantics.
  • Switch to incident response if unexpected files, modified application content, or unauthorized reads are found.
  • Do not test with sensitive system paths or production files.

Triage output: Return a reviewer-ready minimal patch with exposure evidence, authoritative fixed-version evidence, regression tests, deployed-artifact verification, rollback notes, and source links; otherwise return TRIAGE.md with the blocking decision and owner.

Stable reviewed recipe

Remediation authority

CVE-2025-48384: Git Submodule RCE Remediation

Reviewed remediation strategy

  • Upgrade every controlled Git runtime to the fixed release for its active maintenance line: 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, 2.50.1, or a later release that is not in an affected interval. Distro/vendor packages are acceptable when they clearly carry the backported fix.
  • Refresh Docker images, devcontainers, CI runner images, tool caches, workstation setup scripts, SBOMs, dependency reports, and release images that pin or install Git.
  • Remove recursive-submodule checkout for untrusted repositories by default. Require an explicit reviewed trust decision before enabling recursive submodules on external repositories.
  • For untrusted repository analysis that cannot avoid submodules, run the checkout with a fixed Git binary, an empty hooks directory, network and credential isolation, no writable secret mounts, and a reviewed allow-list of submodule URLs.
  • Audit first-party .gitmodules files after upgrading Git. Reject control characters in submodule paths, unexpected symlinks, absolute paths, parent-directory traversal, local filesystem URLs, and unowned submodule remotes.
  • Rotate exposed credentials and inspect job logs if a vulnerable runtime recursively cloned untrusted repositories while secrets or privileged network access were available.

Review the stable recipe source and history

Use AI to implement and verify

  1. Inspect: Inventory every owned instance of git / git; record its location, owner, exact version, exposure, and the read-only evidence used to decide whether it is affected.
  2. Change: Propose the smallest change that implements the stable reviewed recipe: Upgrade every controlled Git runtime to the fixed release for its active maintenance line: 2.43.7 , 2.44.4 , 2.45.4 , 2.46.4 , 2.47.3 , 2.48.2 , 2.49.1 , 2.50.1 , or a later release that is not in an affected interval. Distro/vendor packages are acceptable when they clearly carry the backported fix. Show the exact diff or command plan and dependency impact; do not apply it yet.
  3. Approval: Require the repository, service, or security owner to approve the affected asset, target version, maintenance window, backup, and mutation scope before any write.
  4. Test: After approval, test containment with disposable fixtures covering normalization, separators, links, archives, collisions, and case behavior and save the commands and results.
  5. Rollback: Define failure triggers before the change. If a trigger fires, stop the rollout and use the approved application, database, configuration, or deployment-artifact recovery procedure with a release confirmed not affected by the cited vendor evidence. Never automatically downgrade into an affected version; if no known-safe recovery target exists, isolate the asset and escalate to its owner and vendor. Preserve the failure evidence for triage.
