## What is CVE-2026-24457?

CVE-2026-24457 is a critical path traversal vulnerability in Eclipse GlassFish, published on 5 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An unsafe parsing of OpenMQ's configuration in OpenMQ versions <6.5.2 and <6.9.0, allows a remote attacker to read arbitrary files from a MQ Broker's server. A full exploitation could read unauthorized files of the OpenMQ’s host OS. In some scenarios RCE could be achieved. This is fixed in OpenMQ 6.5.2, 6.9.0, and in GlassFish 7.0.26, 7.1.1, and 8.0.2.

Weakness: CWE-27 (Path Traversal: 'dir/../../filename'), CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2026-24457 and fix it if it is affected.

What it is: CVE-2026-24457 is a critical path traversal vulnerability in Eclipse GlassFish, published on 5 Mar 2026. 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-2026-24457 in the wild and no public exploit code.

Affected product: Eclipse GlassFish. 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.
