@adonisjs/bodyparsernpmDescription
AdonisJS is a TypeScript-first web framework. Prior to versions 10.1.3 and 11.0.0-next.9, a prototype pollution vulnerability in AdonisJS multipart form-data parsing may allow a remote attacker to manipulate object prototypes at runtime. This issue has been patched in versions 10.1.3 and 11.0.0-next.9.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @adonisjs/bodyparser. 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 @adonisjs/bodyparser to 10.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-25754 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-2026-25754 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-2026-25754. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
