{"cve":"CVE-2026-46498","nvd":{"published":"2026-09-15T10:17:04.623","modified":"2026-09-23T18:21:42.327","status":"Awaiting Analysis","description":"Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, OAuthTokenStore reads caller-supplied token identifiers from the shared Core Token Store (CTS) without an OAuth-only namespace, and OAuthAdapter accepts a row whose BLOB claims to contain an OAuth token without binding the trusted CTS type or verifying integrity. An attacker who can place controlled JSON in CTS under a known token identifier, such as through Push Registration followed by an anonymous SNS callback in an enabled realm, can mint OAuth bearer tokens and OpenID Connect ID tokens with chosen subject, client, realm, and scope. The flaw does not by itself create an OpenAM SSO session or grant console access. This issue is fixed in version 16.1.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.6},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/OpenIdentityPlatform/OpenAM/commit/e047b01f24ce5006dbd62b3084b17df2d7835763","https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.1","https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-cj8f-2fhf-826r"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-46498","score":0.00414,"percentile":0.3567,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cj8f-2fhf-826r","url":"https://osv.dev/vulnerability/GHSA-cj8f-2fhf-826r","summary":"OpenAM Arbitrary OAuth Token Minting via Push Registration","modified":"2026-10-28T15:45:09.855030850Z","packages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-oauth2","purl":"pkg:maven/org.openidentityplatform.openam/openam-oauth2","ranges":["<16.1.1"],"fixed":["16.1.1"]}]}],"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).
