{"apiVersion":"1.0","identifier":"CVE-2026-75853","description":"ArcadeDB-s Gremlin wire-protocol plugin (com.arcadedb:arcadedb-gremlin) in versions <= 26.7.3 enforces authentication (SASL PLAIN) but performs no authorization: it never checks database access permissions (canAccessToDatabase) and never binds the authenticated principal into the engine. As a result, any valid server credential — even one provisioned for zero or one unrelated database — can read, write, and drop data in any database on the server by selecting a target database via a traversal-source alias, completely bypassing the engine-s per-type/read-only/UPDATE_SCHEMA ACLs. The issue is fixed in version 26.8.1.","publishedAt":"2026-08-18T12:19:35","lastModifiedAt":"2026-08-18T15:17:14","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75853","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00393,"riskScore":0.91,"affectedProduct":"ArcadeDB","affectedVersions":"<26.8.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75853","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75853","en":"https://www.redsauce.net/en/cves/CVE-2026-75853","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75853","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75853","de":"https://www.redsauce.net/de/cves/CVE-2026-75853","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75853","el":"https://www.redsauce.net/el/cves/CVE-2026-75853"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75853"}}
