CVE-2025-47204
MEDIUMCVE-2025-47204 is a medium-severity (CVSS 6.1) Cross-Site Request Forgery (CSRF) vulnerability in bootstrap-multiselect. O3 Security confirms whether CVE-2025-47204 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Bootstrap Multiselect Vulnerable to CSRF and Reflective XSS via Arbitrary POST Data
Blast Radius
bootstrap-multiselectReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
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).
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | bootstrap-multiselect | all versions | 2.0.0 |
Detection & mitigation playbook
Open-source dependencyDetect
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.
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.
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-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.
