CVE-2026-123545

OpenAM 14.5.1 before 16.1.4 CSRF in OAuth 2.0 Device Flow

OpenAM from 14.5.1 before 16.1.4 contains a cross-site request forgery vulnerability in the OAuth 2.0 device authorization flow that allows attackers to approve device codes when consent is skipped for implied-consent clients. Attackers can start a device authorization and lure a logged-in user to a crafted page, obtaining access and ID tokens to call APIs as that user.

No structured fix or guidance is available here. Check the latest publisher advisory.

CVE-2026-123542

OpenAM before 16.1.4 PKCE Bypass in OAuth 2.0 Device Authorization Flow

OpenAM before 16.1.4 fails to enforce PKCE in the OAuth 2.0 device authorization flow, never validating the code verifier when device codes are exchanged for tokens. Attackers who obtain an approved device code from client logs or shared device storage can redeem it for access and ID tokens to impersonate the user.

CVE-2026-123539

OpenAM before 16.1.4 Stored XSS via OAuth 2.0 Consent Page Display Name

OpenAM before 16.1.4 contains a stored cross-site scripting vulnerability that allows privileged attackers to inject script by placing markup in a user's display name. When the victim reaches the OAuth 2.0 / OpenID Connect consent page, the unencoded name executes script that can steal the OpenAM session cookie to impersonate the user.

GHSA-fq9h-c788-fx73Package fixes recorded

OpenAM has pre-auth Reflected XSS in OAuth2 / OIDC response_mode=form_post via state parameter (FormPostResponse.ftl)

The OAuth 2.0 / OpenID Connect authorization endpoint does not sufficiently sanitize certain user-supplied parameters before incorporating them into the HTML response generated for the form_post response mode. This may allow an attacker to inject content into the rendered page in the context of the OpenAM origin.
