MEDIUMVert.x STOMP server process client frames that would not send initially a connect frame
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
Impact
A Vert.x STOMP server processes client STOMP frames without checking that the client send an initial CONNECT frame replied with a successful CONNECTED frame. The client can subscribe to a destination or publish message without prior authentication. Any Vert.x STOMP server configured with an authentication handler is impacted.
Patches
The issue is patched in Vert.x 4.4.2 and Vert.x 3.9.16
Workarounds
No trivial workaround.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.vertx:vertx-stomp. 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 io.vertx:vertx-stomp to 3.9.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gvrq-cg5r-7chp 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-gvrq-cg5r-7chp 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-gvrq-cg5r-7chp. 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-gvrq-cg5r-7chp in your dependencies?
O3 detects GHSA-gvrq-cg5r-7chp across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
