## What is CVE-2026-24126?

CVE-2026-24126 is a medium-severity command injection vulnerability in WeblateOrg weblate, published on 18 Feb 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Weblate is a web based localization tool. Prior to 5.16.0, the SSH management console did not validate the passed input while adding the SSH host key, which could lead to an argument injection to `ssh-add`. Version 5.16.0 fixes the issue. As a workaround, properly limit access to the management console.

Weakness: CWE-88 (Improper Neutralization of Argument Delimiters in a Command)

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.
