CVE-2026-29773 is a medium-severity vulnerability affecting Kubewarden, a policy engine for Kubernetes, which allows an attacker with specific non-default "AdmissionPolicy" create permissions to gain read-only access. Exploitation involves crafting a policy that leverages deprecated host-callback APIs to read Ingresses, Namespaces, and Services. This vulnerability (CVSS 4.3) has a network attack vector and low attack complexity, but requires existing low privileges. The impact is limited to read-only access of these three resource types, with no write capabilities or access to sensitive data like Secrets or ConfigMaps. There is currently no evidence of active exploitation, public exploit code, or significant community discussion regarding this vulnerability.
