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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":null,"cwes":["CWE-424"],"references":["https://cna.erlef.org/cves/CVE-2026-82586.html","https://github.com/ash-project/ash_lua/commit/c0dfcd9494766d548178c37df0bd01cff378e1c7","https://github.com/ash-project/ash_lua/security/advisories/GHSA-37jv-wc37-fhcw","https://osv.dev/vulnerability/EEF-CVE-2026-82586"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-82586","score":0.00524,"percentile":0.44452,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
