Brevo — Vulnerabilities & Security Advisories 4

Brevo provides a digital communication platform for email marketing, CRM, and transactional messaging. Historically, vulnerabilities have included stored cross-site scripting (XSS) in email templates, remote code execution (RCE) in file upload features, and privilege escalation flaws in administrative panels. The platform has experienced security incidents, including a 2023 data breach affecting 33 million users where email addresses and IP addresses were exposed. Security assessments often identify input validation weaknesses and insufficient access controls, particularly in user-generated content handling. While the company has addressed reported issues through patches, the persistent presence of multiple CVEs indicates ongoing challenges in secure coding practices across their web applications.
