## What is CVE-2018-1261?

CVE-2018-1261 is a medium-severity path traversal vulnerability in Pivotal Spring Integration Zip, published on 11 May 2018. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

Spring-integration-zip versions prior to 1.0.1 exposes an arbitrary file write vulnerability, which can be achieved using a specially crafted zip archive (affects other archives as well, bzip2, tar, xz, war, cpio, 7z) that holds path traversal filenames. So when the filename gets concatenated to the target extraction directory, the final path ends up outside of the target folder.

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

Check this codebase for CVE-2018-1261 and fix it if it is affected.

What it is: CVE-2018-1261 is a medium-severity path traversal vulnerability in Pivotal Spring Integration Zip, published on 11 May 2018. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2018-1261 in the wild and no public exploit code.

Affected packages and fixed versions:

- org.springframework.integration:spring-integration-zip (Maven): affected all versions; fixed in 1.0.1

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.
