The read action's operation aggregate path in AshLua.Runtime took the field name straight from the Lua call and resolved it with only String.to_existing_atom and Ash.Query.Aggregate.new!, neither of which consults the exposed-field allow-list the normal fields path enforces. A script can therefore read the value of any attribute of any record the actor may read, including private sensitive?: true columns, via resource.read({ operation = {\"list\", \"hashed_password\"} }); min and max give a value oracle. Anyone able to submit or influence a Lua script can reach this.\n\nThis issue affects ash_lua: from 0.1.0 before 0.2.1.","published":"2026-09-07T23:16:52.093","modified":"2026-09-07T23:16:52.093","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/ash-project/ash_lua/commit/c0dfcd9494766d548178c37df0bd01cff378e1c7","label":"ash-project/ash_lua@c0dfcd9"},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82586.html"},{"type":"WEB","url":"https://github.com/ash-project/ash_lua/commit/c0dfcd9494766d548178c37df0bd01cff378e1c7"},{"type":"WEB","url":"https://github.com/ash-project/ash_lua/security/advisories/GHSA-37jv-wc37-fhcw"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-82586"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-07T23:16:52.093"}}
