Zimbra

Zimbra operates a unified messaging and collaboration platform—email, calendar, contacts, and document sharing—deployed across enterprises and service providers as an on-premises or cloud solution. Despite a narrowly focused product line, the platform's prevalence in critical communication infrastructure and its internet-facing attack surface place it among more prominent vendors in the vulnerability landscape. Vulnerabilities affecting Zimbra cluster around web-application weaknesses, notably cross-site scripting, cross-site request forgery, server-side request forgery, and code injection, reflecting the complexity of a rich web interface handling user input and inter-component communication. The exposure reaches moderate severity levels, and a meaningful share has acquired public exploit code, making disclosures in this product line relevant to defenders managing email and collaboration deployments. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
