CVE-2023-23738Network attack vector

Unauthenticated email content spoofing for phishing

Published Jun 3, 2024 · Updated Apr 28, 2026

Injection in Brainstorm Force Spectra Legacy 2.3.0 and earlier allows remote attackers to spoof email content via network requests. Neither the CNA record nor its sole Patchstack reference identifies the affected form endpoint, input field, or output operation that fails to neutralize attacker-controlled content. No authentication or user interaction is required, and the documented integrity impact is limited to content spoofing and phishing rather than data disclosure or service interruption.
