Carrcommunications

Carrcommunications produces a compact line of event-management and scheduling applications, particularly RSVPMaker and its Excel integration, that sit at the intersection of web-facing input handling and file processing. Vulnerabilities affecting the vendor skew strongly toward critical-severity outcomes and frequently acquire public exploit code, clustering around application-layer weaknesses including SQL injection, cross-site scripting, code injection, server-side request forgery, and unrestricted file uploads—patterns endemic to web applications with limited input sanitization and file-handling controls. Defenders should treat this vendor's advisories as requiring prompt attention; live severity, exploitation, and coverage counts are shown alongside this summary.
