GHSA-4vpr-xfrp-cj64
HIGHGHSA-4vpr-xfrp-cj64 is a high-severity (CVSS 7.3) CWE-863 vulnerability in org.springframework.security:spring-security-config. 3 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-4vpr-xfrp-cj64 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Spring Security's authorization rules can be misconfigured when using multiple servlets

Description
Spring Security versions 5.8 prior to 5.8.5, 6.0 prior to 6.0.5, and 6.1 prior to 6.1.2 could be susceptible to authorization rule misconfiguration if the application uses requestMatchers(String) and multiple servlets, one of them being Spring MVC’s DispatcherServlet. (DispatcherServlet is a Spring MVC component that maps HTTP endpoints to methods on @Controller-annotated classes.)
Specifically, an application is vulnerable when all of the following are true:
- Spring MVC is on the classpath
- Spring Security is securing more than one servlet in a single application (one of them being Spring MVC’s DispatcherServlet)
- The application uses requestMatchers(String) to refer to endpoints that are not Spring MVC endpoints
An application is not vulnerable if any of the following is true:
- The application does not have Spring MVC on the classpath
- The application secures no servlets other than Spring MVC’s DispatcherServlet
- The application uses requestMatchers(String) only for Spring MVC endpoints

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.security:spring-security-config. 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 org.springframework.security:spring-security-config to 5.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4vpr-xfrp-cj64 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-4vpr-xfrp-cj64 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-4vpr-xfrp-cj64. 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-4vpr-xfrp-cj64 in your dependencies?
O3 detects GHSA-4vpr-xfrp-cj64 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
