Cross-site Scripting in eZFind spellcheck

GHSA-9cq2-pcgr-8h62

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (ezsystems/ezfind-ls 2017.12.0.1, 5.4.11.1, 5.3.6.1), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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 "searchextras.spellcheckcollation" is followed by the "wash" operator, like this: {$searchextras.spellcheckcollation|wash} To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually: https://github.com/ezsystems/ezfind/commit/51c17ea9b1231c20db8221f34d01c649060f1e91

# Patch Next advisory brief: GHSA-9cq2-pcgr-8h62

Advisory: Cross-site Scripting in eZFind spellcheck
IDs: GHSA-9cq2-pcgr-8h62
Record: https://patchnext.com/advisories/ghsa-9cq2-pcgr-8h62 (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: ezsystems/ezfind-ls 2017.12.0.1, 5.4.11.1, 5.3.6.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist ezsystems/ezfind-ls: affected >= 2017.12.0, < 2017.12.0.1; >= 5.4.0, < 5.4.11.1; >= 5.3.0, < 5.3.6.1; fixed in 5.4.11.1, 2017.12.0.1, 5.3.6.1

## Suggested inspection (read-only)
- Packagist ezsystems/ezfind-ls: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on ezsystems/ezfind-ls.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
