The generated SQL therefore removes only literal spaces and leaves tabs, newlines, carriage returns, and form feeds in place, whereas String.trim/1 in Elixir removes them all. Any Ash filter, validation, or identity that relies on string\\_trim/1 then behaves differently depending on whether Ash pushes the expression down to SQL or evaluates it in memory, so padded input can register a near-duplicate value or slip past a trimmed comparison.\n\nThis issue affects ash\\_sql: from 0.1.0 before 0.7.1.\n\n## Configuration\n\nAn application must use string\\_trim/1 in a filter, validation, calculation, or identity that an attacker-influenced string field flows through, where the trimmed value is compared for equality or uniqueness.","id":"EEF-CVE-2026-80227","modified":"2026-08-30T11:53:36.109487Z","published":"2026-08-30T11:53:35.548Z","references":[{"type":"ADVISORY","url":"https://github.com/ash-project/ash_sql/security/advisories/GHSA-76wx-w7ww-5xfq"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-80227.html"},{"type":"FIX","url":"https://github.com/ash-project/ash_sql/commit/1b11b5d8bc5321e2e6acac21594ef08f61986117"},{"type":"PACKAGE","url":"https://hex.pm/packages/ash_sql"}],"related":[],"schema_version":"1.7.3","severity":[{"score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","type":"CVSS_V4"}],"summary":"SQL string_trim removes only spaces, diverging from in-memory trimming in AshSql","upstream":[]}
