Atoms are never garbage collected and the table is capped, so flooding either event with random names mints a new atom per request until the VM aborts, taking down every application on the node. The fix resolves the submitted resource/domain against the known shown resources and maps calculation keys to declared arguments, so no client-supplied string is interned.\n\nThis issue affects ash_admin: from 0.1.0 before 1.3.1.","published":"2026-08-31T02:22:15.099Z","modified":"2026-09-01T03:46:37.413392209Z","cvss":null,"epss":{"score":0.00268,"percentile":0.18593,"asOf":"2026-08-31"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":{"url":"https://github.com/ash-project/ash_admin/commit/731dffa09416d68f4ad3a0b6ee146b285ca0083b","label":"ash-project/ash_admin@731dffa"},"references":[{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-82722.html"},{"type":"WEB","url":"https://github.com"},{"type":"WEB","url":"https://osv.dev/vulnerability/EEF-CVE-2026-82722"},{"type":"WEB","url":"https://repo.hex.pm"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82722.json"},{"type":"ADVISORY","url":"https://github.com/ash-project/ash_admin/security/advisories/GHSA-wcr6-9rrw-5jhv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82722"},{"type":"FIX","url":"https://github.com/ash-project/ash_admin/commit/731dffa09416d68f4ad3a0b6ee146b285ca0083b"},{"type":"PACKAGE","url":"https://github.com/ash-project/ash_admin"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-01T03:46:37.413392209Z"}}
