{"id":"CVE-2026-77125","summary":"Nexus Repository 3 - Incorrect Authorization on Blobstore Group Endpoints","details":"A vulnerability was identified in Sonatype Nexus Repository 3 in which two blobstore group management REST API endpoints did not correctly enforce the intended authorization check. A user granted only the nexus:blobstores:create permission could invoke these endpoints to convert an existing blobstore into a group blobstore, an action that should require the nexus:blobstores:update permission instead. This could result in unauthorized modification of blobstore configuration without administrator approval. The nexus:blobstores:create permission is a named permission that must be explicitly granted by an administrator; it is not held by default.","modified":"2026-09-24T03:45:46.235515086Z","published":"2026-09-02T17:03:25.295Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77125.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"3.19.0"},{"fixed":"3.96.0"}]}],"cna_assigner":"Sonatype","cwe_ids":["CWE-863"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77125.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77125"},{"type":"ADVISORY","url":"https://support.sonatype.com/hc/en-us/articles/54643114434451/"},{"type":"FIX","url":"https://help.sonatype.com/en/sonatype-nexus-repository-3-96-0-release-notes.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sonatype/nexus-public","events":[{"introduced":"d3abc7c7b1c9ea55aa5b7883e2dad1dc3cc5c356"},{"fixed":"3864d782ba6fa207d390ea66571fd523c6245e4e"}],"database_specific":{"cpe":"cpe:2.3:a:sonatype:nexus_repository_manager:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.19.0"},{"fixed":"3.96.0"}],"source":"CPE_RANGE"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77125.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
