Check this codebase for CVE-2026-48619 and fix it if it is affected.

What it is: CVE-2026-48619 is a medium-severity denial of service vulnerability in Nodejs Node.js, published on 26 Jun 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-2026-48619 in the wild and no public exploit code.

Affected packages and fixed versions:
- node (Bitnami): affected from 22.22.3; fixed in 22.23.0, 24.17.0, 26.3.1
- node-min (Bitnami): affected from 22.22.3; fixed in 22.23.0, 24.17.0, 26.3.1

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.
