CVE-2026-104803: WPCOM Member: Privilege escalation or authentication bypass

An unauthenticated attacker can abuse the social-login callback init handler’s uuid/code flow. Missing nonce/OAuth-state binding and globally shared storage allow attacker-written login data to be consumed by weapp_new_user, which resolves a forged openid and calls wp_set_auth_cookie. Exploitation requires a configured social provider and a known or discoverable victim openid/unionid. It can impersonate that account, including an administrator when those prerequisites hold; the export does not name a complete callback URL. Affected versions: <= 1.7.27. No fixed release is confirmed. Upstream 1.8.0.1 is available and may resolve the issue, but the official changelog does not clearly establish that it fixes this CVE.
