Because put_new defers to the handler only when the handler itself set :path, a sanitizing handler that returns a fresh map or deletes :path has that decision reverted. The re-injected path comes from build_error_path/5, which falls back to raw internal Ash attribute and argument names when no field_names mapping is configured. A validation failure on a non-exposed or nested field therefore returns internal names in the GraphQL error path, defeating the application's redaction.\n\nThis issue affects ash_graphql: from 1.9.0 before 1.11.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
