## What is CVE-2026-55675?

CVE-2026-55675 is a critical code injection vulnerability in saltyorg docs, published on 13 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Salty documentation repository builds and deploys the docs.saltbox.dev website. Prior to commit 649c9aea2daef1168eeb0415b44e65dbbde9f220, .github/workflows/trigger-pr-build.yml records an untrusted fork commit in the pr_info artifact, and the secret-bearing workflow_run job in .github/workflows/build-pr.yml checks out that commit before running pip install -r requirements.txt. A fork pull request can therefore supply attacker-authored setup.py or PEP 517 build hooks whose installation code executes in the privileged base-repository workflow with CF_API_TOKEN, GH_TOKEN, MKDOCS_GIT_COMMITTERS_APIKEY, and a write-capable GITHUB_TOKEN, allowing secret disclosure and follow-on compromise. The vulnerability is not caused by the repository-fork guard, and the demonstrated path requires attacker control of fork content rather than merely the artifact metadata. This vulnerability is fixed with commit 649c9aea2daef1168eeb0415b44e65dbbde9f220.

Weakness: CWE-94 (Improper Control of Generation of Code), CWE-829 (Inclusion of Functionality from Untrusted Control Sphere), CWE-1357 (Reliance on Insufficiently Trustworthy Component)

Check this codebase for CVE-2026-55675 and fix it if it is affected.

What it is: CVE-2026-55675 is a critical code injection vulnerability in saltyorg docs, published on 13 Oct 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-2026-55675 exists.

Affected product: saltyorg docs. 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.
