Elastic — Vulnerabilities & Security Advisories 396

Browse all 396 CVE security advisories affecting Elastic. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Elastic operates as a search and analytics engine, primarily powering the ELK Stack for log management and data visualization. With 223 recorded Common Vulnerabilities and Exposures, the platform has historically been susceptible to critical flaws, including remote code execution, cross-site scripting, and privilege escalation vulnerabilities. These issues often stem from improper input validation and authentication bypasses within its Java-based architecture. Notable incidents involve unauthorized access to sensitive data through exposed APIs, highlighting risks associated with default configurations. The sheer volume of CVEs suggests persistent challenges in securing complex distributed systems. While the software remains a cornerstone for enterprise search, its extensive attack surface requires rigorous patching and strict access controls to mitigate the high probability of exploitation by threat actors targeting its widespread deployment infrastructure.
