  "title": "Secret disclosure and two-factor bypass in @better-auth/electron",
  "summary": "Servers using @better-auth/electron from 1.5.0-beta.12 onward may disclose authentication and social-provider client secrets during sign-in, allowing a user who can authenticate to impersonate other known-email users. A separate second-factor bypass affects deployments that enable twoFactor(), register electron() first, and permit password sign-in for users enrolled in two-factor authentication.",
  "mitigation": "Upgrade both @better-auth/electron and better-auth to 1.7.16, or to 1.8.0-beta.5 on the beta release line. Rotate the authentication secret and all configured social-provider client secrets; remove the electron() plugin until upgrade if necessary.",
