## What is CVE-2022-26049?

CVE-2022-26049 is a medium-severity path traversal vulnerability in com.diffplug.gradle:goomph, published on 11 Sep 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This affects the package com.diffplug.gradle:goomph before 3.37.2. It allows a malicious zip file to potentially break out of the expected destination directory, writing contents into arbitrary locations on the file system. Overwriting certain files/directories could allow an attacker to achieve remote code execution on a target system by exploiting this vulnerability. **Note:** This could have allowed a malicious zip file to extract itself into an arbitrary directory. The only file that Goomph extracts is the p2 bootstrapper and eclipse metadata files hosted at eclipse.org, which are not malicious, so the only way this vulnerability could have affected you is if you had set a custom bootstrap zip, and that zip was malicious.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

What it is: CVE-2022-26049 is a medium-severity path traversal vulnerability in com.diffplug.gradle:goomph, published on 11 Sep 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-26049 in the wild and no public exploit code.

Affected packages and fixed versions:
- com.diffplug.gradle:goomph (Maven): affected all versions; fixed in 3.37.2
- com.diffplug.gradle:goomph (Maven): affected all versions; fixed in 3.37.2

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.
