Formio improperly authorized permission elevation through specially crafted request path
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Security Advisory: Unauthorized permission elevation through specially crafted request path
Summary: A flaw in path handling could allow an attacker to access protected API endpoints by sending a crafted request path. This issue could result in unauthorized data disclosure under certain configurations.
Impact: In affected configurations, an unauthenticated or unauthorized request could retrieve data from endpoints that should be protected.
Affected versions: <= 3.5.6 <= 4.4.2
Fixed in: 3.5.7 4.4.3
Mitigation / Workarounds: Upgrade to 3.5.7 or later.
Disclosure timeline: Discovered 2025-05-22; fixed 2025-05-30; publicly disclosed 2025-12.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for formio. 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 formio to 3.5.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m654-769v-qjv7 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 GHSA-m654-769v-qjv7 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-m654-769v-qjv7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m654-769v-qjv7 in your dependencies?
O3 detects GHSA-m654-769v-qjv7 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
