{"id":"CVE-2026-62280","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-62280","summary":"OpenAM Reflected XSS in the OAuth2/OIDC `wap` consent page","details":"### Description\nThe OAuth2/OIDC consent page rendered for `display=wap` authorize requests reflected several request-derived values into the HTML response without escaping. An attacker who induces a user with an active OpenAM session to follow a crafted authorize link can execute arbitrary JavaScript in the OpenAM origin.\n\nThis is the same vulnerability class as CVE-2026-44203; that fix did not cover this code path.\n\n### Impact\nArbitrary JavaScript execution in the OpenAM origin in the victim's authenticated context — enabling session/cookie theft, CSRF-token exfiltration, and actions on behalf of the victim, up to administrative takeover if the victim is an administrator. Reachable on any deployment with at least one registered OAuth2 client; no attacker-controlled client and no special configuration required.\n\n### Mitigation\n- Upgrade to 16.1.2 (or later).\n- Until then, restrict/limit access to the OAuth2 authorize endpoint and treat unsolicited `display=wap` authorize links as untrusted.","published":"2026-07-24T21:09:36Z","modified":"2026-07-24T21:16:20.126594987Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-oauth2","fixedVersion":"16.1.2"}],"fix":{"url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/98cee2dfe701c2e16e5bcee34e6fd9d913925118","label":"OpenIdentityPlatform/OpenAM@98cee2d"},"references":[{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-vqxv-6xrh-49cp"},{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/commit/98cee2dfe701c2e16e5bcee34e6fd9d913925118"},{"type":"PACKAGE","url":"https://github.com/OpenIdentityPlatform/OpenAM"},{"type":"WEB","url":"https://github.com/OpenIdentityPlatform/OpenAM/releases/tag/16.1.2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-24T21:16:20.126594987Z"}}
