Armeria is a microservice framework 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. Prior to version 1.24.3, the Armeria decorators might not invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer. Version 1.24.3 contains a patch for this issue.
CVE-2023-38493
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 58% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
