erxesnpmDescription
Erxes, an experience operating system (XOS) with a set of plugins, is vulnerable to cross-site scripting in versions 0.22.3 and prior. This results in client-side code execution. The victim must follow a malicious link or be redirected there from malicious web site. There are no known patches.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for erxes, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of erxes for GHSA-g9ph-r9hc-34r8. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
