CVE-2026-22726
Last modified
CVE-2026-22726 is a medium-severity vulnerability rated 5/10 on the CVSS scale. Route Services can be leveraged to send app traffic to network destinations outside of an app's configured egress rules. As a result, a malicious developer with access to Cloudfoundry could configure a route-service that would allow it to send requests to HTTP services on internal networks reachable by the Gorouter, which may not have previously had direct access from outside networks, or from the application. Routing release: affected from v0.118.0 through v0.371.0 (inclusive); upgrade to v0.372.0 or greater. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
