## What is CVE-2023-30855?

CVE-2023-30855 is a medium-severity path traversal vulnerability in Pimcore Pimcore, published on 8 May 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Pimcore is an open source data and experience management platform. Versions of Pimcore prior to 10.5.18 are vulnerable to path traversal. The impact of this path traversal and arbitrary extension is limited to creation of arbitrary files and appending data to existing files. When combined with the SQL Injection, the exported data `RESTRICTED DIFFUSION 9 / 9` can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary PHP code on the server with the permissions of the webserver. Users may upgrade to version 10.5.18 to receive a patch or, as a workaround, apply the patch manually.

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

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.
