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.\n\n## Affected\n\n- `nexus_repository_manager >= 3.19.0, < 3.96.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `nexus_repository_manager 3.96.0`","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":209244,"id":"CVE-2026-77125","ts":1790100526465,"field":"cvss","old":null,"new":"7.1"},{"seq":209243,"id":"CVE-2026-77125","ts":1790100526465,"field":"severity","old":"none","new":"high"}]}
