GHSA-c53x-wwx2-pg96 is a medium-severity (CVSS 6.5) vulnerability in @berslucas/liljs. O3 Security confirms whether GHSA-c53x-wwx2-pg96 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Cross-Site Scripting in @berslucas/liljs
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@berslucas/liljsnpmDescription
Versions of @berslucas/liljs prior to 1.0.2 are vulnerable to Cross-Site Scripting (XSS). The package uses the unsafe innerHTML function without sanitizing input, which may allow attackers to execute arbitrary JavaScript on the victim's browser.
Recommendation
Upgrade to version 1.0.2 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @berslucas/liljs. 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 @berslucas/liljs to 1.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c53x-wwx2-pg96 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 GHSA-c53x-wwx2-pg96 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 GHSA-c53x-wwx2-pg96. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-c53x-wwx2-pg96 in your dependencies?
O3 detects GHSA-c53x-wwx2-pg96 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
