Description

Versions of swagger-ui prior to 3.0.13 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize YAML files imported from URLs or copied-pasted. This may allow attackers to execute arbitrary JavaScript.

Recommendation

Upgrade to version 3.0.13 or later.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for swagger-ui. 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.

  2. Fix

    Update swagger-ui to 3.0.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-388g-jwpg-x6j4 is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-388g-jwpg-x6j4 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-388g-jwpg-x6j4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
