{"id":"CVE-2026-86522","published":"2026-09-17T14:17:46.313","lastModified":"2026-09-18T18:16:18.527","description":"Improper Output Neutralization for Logs vulnerability in team-alembic AshAuthentication allows an unauthenticated attacker to forge application log entries by submitting a password reset identity containing newlines or control characters.\n\nAshAuthentication.Strategy.Password.RequestPasswordReset.run/3 interpolates the identity argument, the email or username taken straight from the reset request, into its Logger.warning/1 heredocs without escaping, truncating or type-restricting it. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-117"],"vendors":[],"products":[],"references":[{"url":"https://cna.erlef.org/cves/CVE-2026-86522.html","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/commit/3954f277929712755aef57a4a3a821688f121316","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/commit/57c7cc3236bef0fa9da19cb315414f216488866d","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/commit/fd19358bf0eee53ef13dcf17cc499bd4fb393981","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/security/advisories/GHSA-wg7g-r393-vr3g","tags":[]},{"url":"https://osv.dev/vulnerability/EEF-CVE-2026-86522","tags":[]}],"exploitRefs":[{"url":"https://github.com/team-alembic/ash_authentication/commit/3954f277929712755aef57a4a3a821688f121316","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/commit/57c7cc3236bef0fa9da19cb315414f216488866d","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/commit/fd19358bf0eee53ef13dcf17cc499bd4fb393981","tags":[]},{"url":"https://github.com/team-alembic/ash_authentication/security/advisories/GHSA-wg7g-r393-vr3g","tags":[]}],"hasPoc":true,"ai":null}
