Attackers can exploit the missing allowlist validation and absent admin-level authorization check in StoreUserRequest to mass-assign the Admin role directly to the User model, granting access to privileged features. rConfig Pro and Enterprise are not affected.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-915"],"references":["https://github.com/rconfig/rconfig/commit/84822f4051ed97d651b1b4d191c6da2aa8c3c037","https://github.com/rconfig/rconfig/pull/325","https://github.com/rconfig/rconfig/releases/tag/core-8.2.8","https://www.vulncheck.com/advisories/rconfig-privilege-escalation-via-users-api-role-field"],"products":["rconfig:rconfig"],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-63102","score":0.00334,"percentile":0.26572,"date":"2026-10-25"},"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).
