Ash resources routinely use user-settable string primary keys (slugs, emails). Because Plug.Conn.Query resolves duplicate parameters last-wins and primary_key is interpolated last, a stored key such as foo&action_type=destroy injects parameters that override the link, so an admin clicking edit is sent to a destroy form or an arbitrary resource; a # truncates the query into a fragment. The fix builds every link with URI.encode_query/1, encoding all interpolated values.\n\nThis issue affects ash_admin: from 0.3.0-rc.0 before 1.3.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":2.0},"cvss_v3":null,"cwes":["CWE-116"],"references":["https://cna.erlef.org/cves/CVE-2026-82681.html","https://github.com/ash-project/ash_admin/commit/8e8ef91e8ba07498053887c6212f8b0f08178df6","https://github.com/ash-project/ash_admin/security/advisories/GHSA-j89q-xjrh-c26p","https://osv.dev/vulnerability/EEF-CVE-2026-82681","https://github.com/ash-project/ash_admin/security/advisories/GHSA-j89q-xjrh-c26p"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-82681","score":0.00466,"percentile":0.40356,"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).
