Summary
Cross-site Scripting in eZFind spellcheck
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:

Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-9CQ2-PCGR-8H62? GHSA-9CQ2-PCGR-8H62 is a high-severity cross-site scripting (XSS) vulnerability in ezsystems/ezfind-ls (composer), affecting versions >= 2017.12.0, < 2017.12.0.1. It is fixed in 2017.12.0.1, 5.4.11.1, 5.3.6.1. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- Which versions of ezsystems/ezfind-ls are affected by GHSA-9CQ2-PCGR-8H62? ezsystems/ezfind-ls (composer) versions >= 2017.12.0, < 2017.12.0.1 is affected.
- Is there a fix for GHSA-9CQ2-PCGR-8H62? Yes. GHSA-9CQ2-PCGR-8H62 is fixed in 2017.12.0.1, 5.4.11.1, 5.3.6.1. Upgrade to this version or later.
- Is GHSA-9CQ2-PCGR-8H62 exploitable, and should I be worried? Whether GHSA-9CQ2-PCGR-8H62 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-9CQ2-PCGR-8H62 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
