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.","cvss_v4":{"vector":"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","score":6.3},"cvss_v3":null,"cwes":["CWE-117"],"references":["https://cna.erlef.org/cves/CVE-2026-86522.html","https://github.com/team-alembic/ash_authentication/commit/3954f277929712755aef57a4a3a821688f121316","https://github.com/team-alembic/ash_authentication/commit/57c7cc3236bef0fa9da19cb315414f216488866d","https://github.com/team-alembic/ash_authentication/commit/fd19358bf0eee53ef13dcf17cc499bd4fb393981","https://github.com/team-alembic/ash_authentication/security/advisories/GHSA-wg7g-r393-vr3g"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-86522","score":0.00737,"percentile":0.54506,"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).
