Check this codebase for GHSA-f3wf-q4fj-3gxf and fix it if it is affected.
What it is: GHSA-f3wf-q4fj-3gxf is a denial of service vulnerability in typo3/cms, published on 7 Jun 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-f3wf-q4fj-3gxf in the wild and no public exploit code.
Affected packages and fixed versions:
- typo3/cms (Packagist): affected from 7.0.0; fixed in 7.6.32
- typo3/cms (Packagist): affected from 7.0.0; fixed in 7.6.32
- typo3/cms (Packagist): affected from 8.0.0; fixed in 8.7.21

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.

Official description
Online Media Asset Handling (*
.youtube and *.vimeo files) in the TYPO3 backend is vulnerable to denial of service. Putting large files with according file extensions results in high consumption of system resources. This can lead to exceeding limits of the current PHP process which results in a dysfunctional backend component. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.Which versions are affected by GHSA-f3wf-q4fj-3gxf?
