CVE-2026-119705

CVSS 6.9 (medium) · published 2026-10-30

SerpBear before 3.1.1 contains a missing authentication vulnerability in pages/api/notify.ts that allows remote unauthenticated attackers to trigger notification emails because verifyUser() is never called. Attackers can repeatedly POST to /api/notify, optionally with a domain parameter, to exhaust SMTP rate limits, trigger provider abuse flags and flood recipients.

Weakness: CWE-306
