Constant Contact — Vulnerabilities & Security Advisories 6

Constant Contact provides email marketing and digital campaign management services for small businesses. Historically, the platform has been susceptible to cross-site scripting (XSS) and remote code execution vulnerabilities, often through improper input validation and insecure API endpoints. While no major public security incidents have been widely documented, the six recorded CVEs highlight recurring issues in user input handling and access control. The platform's web-facing nature and integration with third-party services create potential attack surfaces, though the company has typically addressed vulnerabilities through timely patches. Security researchers have noted that while the vulnerabilities are generally low to medium severity, their prevalence in marketing platforms warrants regular security assessments.
