CVE-2018-6561
MEDIUMCVE-2018-6561 is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in dijit. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2018-6561 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dijit. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update dijit to 1.13.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-6561 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2018-6561 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2018-6561. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
