formionpmDescription
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update formio to 3.5.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-67718 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-67718 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-67718. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
