## What is GHSA-9cq2-pcgr-8h62?

GHSA-9cq2-pcgr-8h62 is a cross-site scripting vulnerability in ezsystems/ezfind-ls, published on 15 May 2024. 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

This security advisory fixes a vulnerability in the legacy eZ Find extension, which can be used with the LegacyBridge in eZ Platform. It affects sites using the "Did you mean...?" spell check / search suggestion feature. This feature is vulnerable to Cross-site Scripting (XSS) injection (reflected XSS). The update adds the necessary escaping of injected code. If you're affected, we recommend that you install it as soon as possible.
 
If you have custom search templates, please make sure you update these as well. Ensure that "search_extras.spellcheck_collation" is followed by the "wash" operator, like this:
{$search_extras.spellcheck_collation|wash}
 
To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually:

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.
