{"apiVersion":"1.0","identifier":"CVE-2026-75850","description":"ArcadeDB before 26.8.1 fails to bind the authenticated principal (setCurrentUser) on its batch and time-series HTTP handlers. Because no principal is bound on the worker thread, the engine-s fine-grained per-type ACL layer (LocalBucket.checkPermissionsOnFile) does not execute for these handlers. In deployments that use per-type or per-group ACLs, a user with database access but only limited per-type permissions can read from and write to types they are not authorized to access by submitting requests to the batch/time-series endpoints. Deployments that rely solely on database-level access control are not affected.","publishedAt":"2026-08-18T12:19:35","lastModifiedAt":"2026-08-19T15:18:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75850","cvssScore":4.2,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","epssProbability":0.0016,"riskScore":0.43,"affectedProduct":"ArcadeDB","affectedVersions":"<26.8.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75850","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75850","en":"https://www.redsauce.net/en/cves/CVE-2026-75850","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75850","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75850","de":"https://www.redsauce.net/de/cves/CVE-2026-75850","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75850","el":"https://www.redsauce.net/el/cves/CVE-2026-75850"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75850"}}
