### Official description

Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by an information disclosure vulnerability. Through the PUK signature functionality, an administrator will not have access to the current p12 certificate and password. When accessing this functionality, the administrator has the option to replace the current certificate and it is not possible to view the certificate password (p12) already deployed on the platform. The replacement p12 certificate returns to users in base64 with its password, which can be accessed by non-administrator users.

Exploitation: There is no known exploitation of CVE-2020-36127 in the wild and no public exploit code.

Affected product: n/a. 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.
