{"id":"CVE-2026-52744","summary":"GoCD is vulnerable to authorization bypass via fetch artifact autosuggestion API","details":"GoCD is a continuous deliver server. From 20.2.0 until 26.1.0, the internal GoCD UI fetch-artifact auto-suggestion API at /go/api/internal/pipelines/**/upstream does not adequately authorize access to upstream dependency data. An authenticated user can retrieve inter-pipeline dependency hierarchy details and user-defined pipeline, stage, job, and artifact plugin reference names that the user cannot otherwise view in the UI. The endpoint is read-only and does not permit modification of pipeline data. This issue is fixed in version 26.1.0.","aliases":["GHSA-mvpm-hmc9-2q8p"],"modified":"2026-09-24T08:41:43.363132Z","published":"2026-09-23T17:58:52.039Z","database_specific":{"cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52744.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/52xxx/CVE-2026-52744.json"},{"type":"FIX","url":"https://github.com/gocd/gocd/commit/ce9602d7bb27dcb89bf8fc15eb859306cdc8995c"},{"type":"WEB","url":"https://github.com/gocd/gocd/releases/tag/26.1.0"},{"type":"ADVISORY","url":"https://github.com/gocd/gocd/security/advisories/GHSA-mvpm-hmc9-2q8p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-52744"},{"type":"WEB","url":"https://www.gocd.org/releases/#26-1-0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gocd/gocd","events":[{"introduced":"0cb6660ad91a19a4064e6537374c896506add24a"},{"fixed":"55b7b460510bb739c1ae6d226ff7fb650596dca2"}],"database_specific":{"extracted_events":[{"introduced":"20.2.0"},{"fixed":"26.1.0"}],"source":"AFFECTED_FIELD"}}],"versions":["25.4.0","25.3.0","25.2.0","25.1.0","24.5.0","24.4.0","24.3.0","24.2.0","24.1.0","23.5.0","23.4.0","23.3.0","23.2.0","23.1.0","22.3.0","22.2.0","22.1.0","21.4.0","21.3.0","21.2.0","21.1.0","20.10.0","20.9.0","20.8.0","20.7.0","20.6.0","20.5.0","20.4.0","20.3.0","20.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-52744.json","vanir_signatures_modified":"2026-09-24T08:41:43Z","vanir_signatures":[{"id":"CVE-2026-52744-1edf0217","signature_type":"Line","signature_version":"v1","source":"https://github.com/gocd/gocd/commit/55b7b460510bb739c1ae6d226ff7fb650596dca2","target":{"file":"server/src/test/java/com/thoughtworks/go/server/service/ConsoleServiceTest.java"},"deprecated":false,"digest":{"line_hashes":["293644107583814706305313834881514248581","43526100860380261015420273856821442599","157233936825244187698220557484897351053"],"threshold":0.9}},{"deprecated":false,"digest":{"function_hash":"250222003766494194465964995240362262739","length":800},"id":"CVE-2026-52744-27d5397f","signature_type":"Function","signature_version":"v1","source":"https://github.com/gocd/gocd/commit/55b7b460510bb739c1ae6d226ff7fb650596dca2","target":{"file":"server/src/test/java/com/thoughtworks/go/server/service/ConsoleServiceTest.java","function":"shouldReturnUsefulErrorIfMoveConsoleArtifactsFails"}}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
