Dify Multi-Tenant Isolation Failures Enable Cross-Tenant Chat and File Exfiltration
Four high-severity CVEs in Dify exposed cross-tenant data flows through missing validation in tracing and plugin components. The flaws persisted for 18 months alongside a known PDFium vulnerability. This case illustrates systemic tenant-isolation weaknesses now appearing across multiple LLMOps platforms.
Mainstream reporting framed the issue as an isolated patch cycle. The deeper signal is that default multi-tenant controls in open-source AI control planes remain insufficient for production isolation, a gap procurement databases for defense-adjacent AI pilots are now surfacing. Organizations running shared Dify instances must assume prior data exposure until full audit logs are reviewed.
Zafran: Within 120 days at least three additional open-source LLM platforms will disclose equivalent tenant-validation bypasses affecting shared cloud instances.
