{"apiVersion":"1.0","identifier":"CVE-2026-75851","description":"ArcadeDB server (com.arcadedb:arcadedb-server) in versions 26.7.3 and earlier fails to propagate the authenticated principal to asynchronous command worker threads. When an HTTP command is submitted with awaitResponse:false, it executes on an async worker whose DatabaseContext has no bound user, causing the scripting authorization gate to become a no-op. A user with only read access to a single database can submit an asynchronous JavaScript (language=js) command via the /api/v1/command endpoint to run code with unrestricted host access (e.g., database.getSecurity().createUser) and create a server-wide administrator, escalating to full administrative control. Fixed in 26.8.1.","publishedAt":"2026-08-18T12:19:35","lastModifiedAt":"2026-08-18T14:18:12","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75851","cvssScore":9.9,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00316,"riskScore":1.02,"affectedProduct":"ArcadeDB","affectedVersions":"<26.8.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75851","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75851","en":"https://www.redsauce.net/en/cves/CVE-2026-75851","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75851","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75851","de":"https://www.redsauce.net/de/cves/CVE-2026-75851","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75851","el":"https://www.redsauce.net/el/cves/CVE-2026-75851"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75851"}}
