# GHSA-fj93-7wm4-8x2g: Cross-Site Scripting in jquery-mobile > Attackers can execute arbitrary JavaScript via reflected XSS in jQuery Mobile by manipulating location hash and unvalidated XHR responses. - **Severity:** Not scored - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** A user has to click or open something - **Fix available:** No - **Published:** 2 Sep 2020 ## What is GHSA-fj93-7wm4-8x2g? GHSA-fj93-7wm4-8x2g is a cross-site scripting vulnerability in jquery-mobile, published on 2 Sep 2020. 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 All version of `jquery-mobile` are vulnerable to Cross-Site Scripting. The package checks for content in `location.hash` and if a URL is found it does an XmlHttpRequest (XHR) to the URL and renders the response with `innerHTML`. It fails to validate the `Content-Type` of the response, allowing attackers to include malicious payloads as part of query parameters that are reflected back to the user. A response such as `{"q":"","results":[]}` would be parsed as HTML and the JavaScript payload executed. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available. ## Which versions are affected by GHSA-fj93-7wm4-8x2g? 2 open source packages ship an affected version, including jquery-mobile. | Package | Ecosystem | Affected | Fixed in | | --- | --- | --- | --- | | `jquery-mobile` | npm | All versions | None | | `jquery-mobile` | npm | All versions | None | ## How do I fix GHSA-fj93-7wm4-8x2g?

What it is: GHSA-fj93-7wm4-8x2g is a cross-site scripting vulnerability in jquery-mobile, published on 2 Sep 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of GHSA-fj93-7wm4-8x2g in the wild and no public exploit code. Affected packages and fixed versions: - jquery-mobile (npm): affected all versions; no fix listed - jquery-mobile (npm): affected all versions; no fix listed 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.
