Red Hat OpenShift Dev Spaces provides a cloud developer workspace server and a browser-based IDE built for teams and organizations. Dev Spaces runs in OpenShift and is well-suited for container-based development. The 3.21 release is based on Eclipse Che 7.102 and uses the DevWorkspace engine to provide support for workspaces based on devfile v2.1 and v2.2. Users still using the v1 standard should migrate as soon as possible. https://devfile.io/docs/2.2.0/migrating-to-devfile-v2 Dev Spaces releases support the latest two OpenShift 4 EUS releases. Users are expected to update to newer OpenShift releases in order to continue to get Dev Spaces updates. https://access.redhat.com/support/policy/updates/openshift#devspaces Security Fix(es): devspaces-code - tar-fs: link following and path traversal via maliciously crafted tar file (CVE-2024-12905) devspaces-traefik - traefik: HTTP client can manipulate custom HTTP headers that are added by Traefik (CVE-2024-45410) - golang.org/x/crypto/ssh: Misuse of ServerConfig.PublicKeyCallback may cause authorization bypass in golang.org/x/crypto (CVE-2024-45337) - golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh (CVE-2025-22869) - golang-jwt/jwt: jwt-go allows excessive memory allocation during header parsing (CVE-2025-30204)
