{"id":"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.","aliases":["GHSA-rh53-xvx2-j327"],"modified":"2026-08-19T03:31:26.343525960Z","published":"2026-08-13T21:59:24.390Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-306","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73842.json"},"references":[{"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/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73842.json"},{"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"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openchoreo/openchoreo","events":[{"introduced":"0"},{"introduced":"98aa8742f7244e7150cc177438d83b9efc5fdece"},{"introduced":"f2822307a9db82ee6f8f4f41b475252897b4f1a6"},{"fixed":"ab4d9b2ac7c9b4bae184b76f2107a97a07597008"},{"fixed":"6939146711434ad0f427ade431c726b960ddcec8"},{"fixed":"eecc9de11c8f9fb189a2c1f6f2a1e12b7abbdd13"},{"fixed":"50fcae3f1753fd0ac3ae655a3fc080a761c49c04"},{"fixed":"93e6f10953cfc249af2222ddb6730d4b0a729129"},{"fixed":"e3da3c63dcf0895c693cb17ce142ef95e959b62a"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.0.3"},{"introduced":"1.1.0"},{"fixed":"1.1.3"},{"introduced":"1.2.0-rc.1"},{"fixed":"1.2.0-rc.2"}]}}],"versions":["v1.0.2","v1.1.2","v1.1.1","v1.0.1","v1.1.0","v1.0.1-hotfix.1","v1.0.0","v1.0.0-rc.2","v1.0.0-rc.1","v0.17.0","v0.16.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.8.0","v0.7.0","v0.6.0","v0.4.0","v0.5.0","v0.3.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-73842.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
