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, an...

CVE-2026-75853

The com.arcadedb:arcadedb-gremlin plugin (≤26.7.3) enforces SASL PLAIN authentication but skips authorization: it never calls canAccessToDatabase or binds the principal, so any valid credential can read, write, and drop data in any database via a traversal-source alias, bypassing all per-type/rea...
