CVE-2026-22727

Application code injection via unprotected internal endpoints

Published Mar 17, 2026 · Updated Mar 17, 2026

Missing authentication in Cloud Foundry CAPI 1.226.0 and earlier allows attackers to replace application droplets via internal network access. Cloud Foundry identifies unprotected internal endpoints as the locus but does not disclose which handlers omit authentication or how requests authorize droplet replacement. Reachability requires access past the deployment firewall to the internal network; a replacement droplet executes attacker-controlled code in an application environment and exposes application data.
