## What is CVE-2023-27639?

CVE-2023-27639 is a high-severity path traversal vulnerability in n/a, published on 1 Jun 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in the tshirtecommerce (aka Custom Product Designer) component 2.1.4 for PrestaShop.

Only files that can be parsed in XML can be opened. This is exploited in the wild in March 2023.

Check this codebase for CVE-2023-27639 and fix it if it is affected.

What it is: CVE-2023-27639 is a high-severity path traversal vulnerability in n/a, published on 1 Jun 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-27639 exists.

Affected product: n/a. 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.
