## What is CVE-2023-28677?

CVE-2023-28677 is a critical code injection vulnerability in Jenkins Convert To Pipeline Plugin, published on 23 Mar 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Jenkins Convert To Pipeline Plugin 1.0 and earlier uses basic string concatenation to convert Freestyle projects' Build Environment, Build Steps, and Post-build Actions to the equivalent Pipeline step invocations, allowing attackers able to configure Freestyle projects to prepare a crafted configuration that injects Pipeline script code into the (unsandboxed) Pipeline resulting from a convertion by Jenkins Convert To Pipeline Plugin.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Check this codebase for CVE-2023-28677 and fix it if it is affected.

What it is: CVE-2023-28677 is a critical code injection vulnerability in Jenkins Convert To Pipeline Plugin, published on 23 Mar 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-28677 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.jenkins-ci.plugins:convert-to-pipeline (Maven): affected all versions up to 1.0; no fix listed
- org.jenkins-ci.plugins:convert-to-pipeline (Maven): affected all versions up to 1.0; no fix listed

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.
