- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 5 Sep 2022

## What is CVE-2022-3008?

CVE-2022-3008 is a high-severity command injection vulnerability in Debian Debian Linux, published on 5 Sep 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The tinygltf library uses the C library function wordexp() to perform file path expansion on untrusted paths that are provided from the input file. This function allows for command injection by using backticks. An attacker could craft an untrusted path input that would result in a path expansion. We recommend upgrading to 2.6.0 or past commit 52ff00a38447f06a17eab1caa2cf0730a119c751

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command), CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

## Which versions are affected by CVE-2022-3008?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-3008 and fix it if it is affected.

What it is: CVE-2022-3008 is a high-severity command injection vulnerability in Debian Debian Linux, published on 5 Sep 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-3008 exists.

Affected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
