When the actor supplies only the confirmation argument and not the field itself, value resolves through atomic_ref/2 to the field's current stored value, so the mismatch error echoes that stored value back to the actor. Against a confirmation guarding a sensitive attribute, an actor can submit a deliberately wrong confirmation and read the real value from the returned error. The fix reports the actor-supplied confirmation in the error instead of the stored field value.\n\nThis issue affects ash: from 2.17.20 before 3.32.2.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":2.1},"cvss_v3":null,"cwes":["CWE-209"],"references":["https://cna.erlef.org/cves/CVE-2026-82739.html","https://github.com/ash-project/ash/commit/7dfe5f0b1ba4267580ded947dc861351d4dc8e2b","https://github.com/ash-project/ash/security/advisories/GHSA-66cg-vj5m-8w7v","https://osv.dev/vulnerability/EEF-CVE-2026-82739","https://github.com/ash-project/ash/security/advisories/GHSA-66cg-vj5m-8w7v"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-82739","score":0.0018,"percentile":0.07567,"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).
