HIGHPaths contain matrix variables bypass decorators
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
Spring supports Matrix variables.
When Spring integration is used, Armeria calls Spring controllers via TomcatService or JettyService with the path
that may contain matrix variables.
In this situation, the Armeria decorators might not invoked because of the matrix variables.
Let's see the following example:
// Spring controller
@GetMapping("/important/resources")
public String important() {...}
// Armeria decorator
ServerBuilder sb = ...
sb.decoratorUnder("/important/", authService);
If an attacker sends a request with /important;a=b/resources, the request would bypass the authrorizer
Patches
Workarounds
Users can add decorators using regex. e.g. "regex:^/important.*"

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.linecorp.armeria:armeria. 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 com.linecorp.armeria:armeria to 1.24.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wvp2-9ppw-337j 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-wvp2-9ppw-337j 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-wvp2-9ppw-337j. 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-wvp2-9ppw-337j in your dependencies?
O3 detects GHSA-wvp2-9ppw-337j across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
