Description

An issue was discovered in post.php in bootstrap-multiselect (aka Bootstrap Multiselect) 1.1.2. A PHP script in the source code echoes arbitrary POST data. If a developer adopts this structure wholesale in a live application, it could create a Reflective Cross-Site Scripting (XSS) vulnerability exploitable through Cross-Site Request Forgery (CSRF).

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bootstrap-multiselect. 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 bootstrap-multiselect to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-47204 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 CVE-2025-47204 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-2025-47204. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
