The resource logged beside it is passed through `inspect/1`, which would have neutralized the value. A newline in the identity therefore ends the log record, and everything after it is written as a line of its own, so an attacker chooses the severity tag and the content of entries that appear to have come from the application.\n\nThis issue affects ash_authentication: from 4.2.0 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.14.","id":"EEF-CVE-2026-86522","modified":"2026-09-17T13:09:12.417469Z","published":"2026-09-17T13:09:11.572Z","references":[{"type":"ADVISORY","url":"https://github.com/team-alembic/ash_authentication/security/advisories/GHSA-wg7g-r393-vr3g"},{"type":"WEB","url":"https://cna.erlef.org/cves/CVE-2026-86522.html"},{"type":"WEB","url":"https://github.com/team-alembic/ash_authentication/commit/3954f277929712755aef57a4a3a821688f121316"},{"type":"FIX","url":"https://github.com/team-alembic/ash_authentication/commit/fd19358bf0eee53ef13dcf17cc499bd4fb393981"},{"type":"FIX","url":"https://github.com/team-alembic/ash_authentication/commit/57c7cc3236bef0fa9da19cb315414f216488866d"},{"type":"PACKAGE","url":"https://hex.pm/packages/ash_authentication"}],"related":[],"schema_version":"1.7.3","severity":[{"score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N","type":"CVSS_V4"}],"summary":"Log injection via an unescaped password reset identity in AshAuthentication","upstream":[]}
