Check this codebase for CVE-2026-8430 and fix it if it is affected.
What it is: CVE-2026-8430 is a critical vulnerability in SPIP, published on 12 May 2026.
Exploitation: There is no known exploitation of CVE-2026-8430 in the wild and no public exploit code.
Affected product: SPIP. 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.
