## What is CVE-2023-54342?

CVE-2023-54342 is a critical code injection vulnerability in Eclipse Equinox OSGi, published on 5 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Eclipse Equinox OSGi versions 3.8 through 3.18 contain a remote code execution vulnerability in the console interface that allows unauthenticated attackers to execute arbitrary code by exploiting the fork command functionality. Attackers can establish a telnet connection to the OSGi console, perform a telnet handshake, and send fork commands to download and execute malicious Java code, establishing a reverse shell connection.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Check this codebase for CVE-2023-54342 and fix it if it is affected.

What it is: CVE-2023-54342 is a critical code injection vulnerability in Eclipse Equinox OSGi, published on 5 May 2026. 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-2023-54342 exists.

Affected product: Eclipse Equinox OSGi. 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.
