Impact
Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.
Affected versions
Security releases
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.
Remediation advice
Issue has been patched in Build 466 (v1.0.466) by applying the recommended patch from @jquery.

- What is GHSA-V73W-R9XG-7CR9? GHSA-V73W-R9XG-7CR9 is a medium-severity security vulnerability in october/october (composer), affecting versions >= 1.0.319, < 1.0.466. It is fixed in 1.0.466.
- Which packages are affected by GHSA-V73W-R9XG-7CR9?
october/october(composer) (versions >= 1.0.319, < 1.0.466)october/system(composer) (versions >= 1.0.319, < 1.0.466)
- Is there a fix for GHSA-V73W-R9XG-7CR9? Yes. GHSA-V73W-R9XG-7CR9 is fixed in 1.0.466. Upgrade to this version or later.
- Is GHSA-V73W-R9XG-7CR9 exploitable, and should I be worried? Whether GHSA-V73W-R9XG-7CR9 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-V73W-R9XG-7CR9 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.
