How severe is CVE-2024-41956?

CVE-2024-41956 has a CVSS score of 8.1/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-41956?

CVE-2024-41956 affects the following packages: github.com/charmbracelet/soft-serve (Go). Ecosystems affected: Go.

How do I fix CVE-2024-41956?

Update github.com/charmbracelet/soft-serve to 0.7.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-41956 is resolved across your whole dependency graph.

How do I detect CVE-2024-41956 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/charmbracelet/soft-serve, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-41956 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2024-41956 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-41956 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-41956?

CVE-2024-41956 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 44th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-41956?

CVE-2024-41956 is classified as OS Command Injection (CWE-78). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2024-41956 published, and has it been updated?

CVE-2024-41956 was published on August 1, 2024 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

References

n/a.

It is possible for a user who can commit files to a repository hosted by Soft Serve to execute arbitrary code via environment manipulation and Git.

The issue is that Soft Serve passes all environment variables given by the client to git subprocesses. This includes environment variables that control program execution, such as LD_PRELOAD.

This can be exploited to execute arbitrary code by, for example, uploading a malicious shared object file to Soft Serve via Git LFS (uploading it via LFS ensures that it is not compressed on disk and easier to work with). The file will be stored under its SHA256 hash, so it has a predictable name.

This file can then be referenced in LD_PRELOAD via a Soft Serve SSH session that causes git to be invoked. For example:

LD_PRELOAD=/.../data/lfs/1/objects/a2/b5/a2b585befededf5f95363d06d83655229e393b1b45f76d9f989a336668665a2f ssh server git-upload-pack repo

The example LFS file patches a shared library function called by git to execute a shell.
