Description

Description

When the Vaadin Upload's start listener is used to validate metadata about an incoming upload, it is possible to bypass the upload validation. Users of affected versions should apply the upgrade to a more recent Vaadin version.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.vaadin:vaadin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update com.vaadin:vaadin to 14.13.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c7v7-rqfm-f44j 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-c7v7-rqfm-f44j can be triaged on real exposure rather than presence alone.

Tailored to GHSA-c7v7-rqfm-f44j. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
