{"id":"CVE-2026-73842","aliases":["GHSA-rh53-xvx2-j327"],"url":"https://o3.security/vulnerability/CVE-2026-73842","summary":"OpenChoreo: cluster-gateway internal proxy performs no caller authentication and is not read-only — data-plane Secret disclosure and arbitrary Kubernetes mutation","details":"OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.3, 1.1.3, and 1.2.0-rc.2, internal/cluster-gateway/server.go exposed /api/proxy/, /api/exec/, and /api/wirelogs/ on an internal listener without requiring a client certificate or token, allowing any network-reachable caller to read tenant Kubernetes Secrets, mutate workloads, and execute commands across connected data planes. This issue is fixed in versions 1.0.3, 1.1.3, and 1.2.0-rc.2.","published":"2026-08-13T21:59:24.390Z","modified":"2026-08-14T04:04:12.212053496Z","cvss":{"score":9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/openchoreo/openchoreo/commit/50fcae3f1753fd0ac3ae655a3fc080a761c49c04","label":"openchoreo/openchoreo@50fcae3"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73842.json"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/commit/50fcae3f1753fd0ac3ae655a3fc080a761c49c04"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/commit/93e6f10953cfc249af2222ddb6730d4b0a729129"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/commit/e3da3c63dcf0895c693cb17ce142ef95e959b62a"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/pull/4256"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/pull/4258"},{"type":"FIX","url":"https://github.com/openchoreo/openchoreo/pull/4259"},{"type":"WEB","url":"https://github.com/openchoreo/openchoreo/releases/tag/v1.0.3"},{"type":"WEB","url":"https://github.com/openchoreo/openchoreo/releases/tag/v1.1.3"},{"type":"WEB","url":"https://github.com/openchoreo/openchoreo/releases/tag/v1.2.0-rc.2"},{"type":"ADVISORY","url":"https://github.com/openchoreo/openchoreo/security/advisories/GHSA-rh53-xvx2-j327"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73842"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:04:12.212053496Z"}}
