## What is CVE-2021-34630?

CVE-2021-34630 is a medium-severity cross-site scripting vulnerability in GTranslate Pro and GTranslate Enterprise, published on 30 Jul 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

In the Pro and Enterprise versions of GTranslate < 2.8.65, the gtranslate_request_uri_var function runs at the top of all pages and echoes out the contents of $_SERVER['REQUEST_URI']. Although this uses addslashes, and most modern browsers automatically URLencode requests, this plugin is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below, or in cases where an attacker is able to modify the request en route between the client and the server, or in cases where the user is using an atypical browsing solution.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation), CWE-116 (Improper Encoding or Escaping of Output)

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.
