{"id":"CVE-2026-47386","summary":"NocoDB: OAuth Authorization Code Race Condition","details":"NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, two concurrent token-exchange requests using the same OAuth authorization code could each mint a distinct valid (access_token, refresh_token) pair, breaking the single-use guarantee that PKCE relies on. This vulnerability is fixed in 2026.05.1.","aliases":["GHSA-8m7c-hf24-5g47"],"modified":"2026-11-04T02:47:46.834365672Z","published":"2026-06-23T20:12:13.596Z","database_specific":{"cwe_ids":["CWE-362"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47386.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47386.json"},{"type":"ADVISORY","url":"https://github.com/nocodb/nocodb/security/advisories/GHSA-8m7c-hf24-5g47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47386"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nocodb/nocodb","events":[{"introduced":"0"},{"fixed":"080f783384dc6d5ef65699bd5e484bfe1c1b9480"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"2026.05.1"}]},{"source":"DESCRIPTION","range":[{"introduced":"0"},{"fixed":"2026.05.1"}]}]}}],"versions":["v2026.05.1-pre.1","v2026.05.0","v2026.04.5","v2026.04.4","v2026.04.3","v2026.04.2","v2026.04.1","v2026.03.0-pre.01","v2026.01.1","v2026.01.0","v2025.11.0","v2025.10.0","v2025.09.0","v2025.08.0","v2025.07.0","v2025.06.0","v2025.05.0","0.100.2","0.100.1","0.100.0","0.99.2","0.99.1","0.99.0","0.98.4","0.98.3","0.98.2","0.98.1","0.97.0","0.96.4","0.96.0","0.92.4","0.92.3","0.92.2","0.92.0","0.92.1","0.91.10","0.91.9","0.91.8","0.91.7","0.91.6","0.91.1","0.91.0","0.90.11","0.90.10","0.90.9","0.90.8","0.90.7","0.90.4","0.90.3","0.90.1","0.90.0","0.84.16","0.84.15","0.84.14","0.84.13","0.84.12","0.84.10","0.84.9","0.84.8","0.84.7","0.84.6","0.84.3","0.84.2","0.84.1","0.83.8","0.83.6","0.83.5","0.83.4","0.83.3","0.83.2","0.83.1","0.83.0","0.82.0","0.81.1","0.81.0","0.80.0","0.11.46","0.11.45","0.11.44","0.11.43","0.11.42","0.11.41","0.11.40","0.11.39","0.11.36","0.11.34","0.11.33","0.11.31","0.11.30","0.11.29","0.11.28","0.11.26","0.11.22","0.11.25","0.11.24","0.11.23","0.11.21","0.11.20","0.11.19","0.11.18","0.11.17","0.11.16","0.11.15","0.11.14","0.11.12","0.11.11","0.11.10","0.11.9","0.11.7","0.11.6","0.11.5","0.11.4","0.11.3","0.11.1","0.11.0","0.10.6","0.10.5","0.10.4","0.10.3","0.10.2","0.10.1","v0.10.0","0.10.0","0.9","0.4.9","0.4.8","0.4.5","v0.4.4","v0.4.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47386.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
