## What is CVE-2005-4780?

CVE-2005-4780 is a low-severity cross-site scripting vulnerability in n/a, published on 14 Apr 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Cross-site scripting (XSS) vulnerability in Fidra Lighthouse CMS 1.1.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the search parameter in a query_string to the home page. NOTE: The vendor disputes this issue, saying "Lighthouse does not in any way make use of the PHP technology.  [It] is an application server ... A technology like this cannot be susceptible to client-side cross-site-scripting-attacks on its own, but only applications created based on such a technology. This does not only apply to Lighthouse, but also to Perl, PHP or web applications based on Java Servlet technology."  Since the original researcher is known to test demo pages and is sometimes inaccurate, it is likely that this issue will be REJECTED

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.
