## What is CVE-2023-50461?

CVE-2023-50461 is a high-severity code injection vulnerability in TYPO3 direct_mail, published on 14 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An issue was discovered in the direct_mail (aka Direct Mail) extension through 9.5.1 for TYPO3. The Configuration backend module of the extension allows an authenticated user to write to an arbitrary TSConfig page for folders configured as Direct Mail. Exploiting this may lead to Configuration Injection (TYPO3 10.4 and above) and to Arbitrary Code Execution (TYPO3 9.5 and below). A valid backend user account, with access to the Direct Mail Configuration backend module, is needed to exploit this.

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.
