CVE-2026-48545 WRITEUP MEDIUM WRITEUP
Gradio < 6.15.0 Cookie Injection via Shared Proxy Client
Gradio before version 6.15.0 contains a cookie injection vulnerability that allows remote attackers to perform cross-Space session fixation by exploiting a shared module-level HTTP client used across all users in the reverse proxy endpoint. Attackers controlling any HF Space can return a parent-domain cookie that the shared client stores and automatically replays into all subsequent proxy requests to other legitimate Spaces, affecting all users of the same Gradio deployment.
CVSS 6.8
CVE-2026-41947 WRITEUP CRITICAL WRITEUP
Dify v1.14.1 Authorization Bypass via Trace Configuration Endpoints
Dify before version 1.14.2 contains an authorization bypass vulnerability that allows authenticated editor users to set and enable trace configurations for any application regardless of tenant ownership. Attackers can exploit missing tenant ownership checks in the trace configuration endpoints to redirect all messages and responses from victim applications to attacker-controlled LLM trace providers. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.
CVSS 9.1
CVE-2026-41949 WRITEUP MEDIUM WRITEUP
Dify v1.14.1 Authorization Bypass via File Preview Endpoint
Dify before version 1.14.2 contains an authorization bypass vulnerability in the file preview endpoint that allows any authenticated user to read up to 3,000 characters of any uploaded document across all tenants and workspaces using only the file's UUID. Attackers can access the /console/api/files/{file_id}/preview endpoint with an intercepted file UUID to extract sensitive content from documents without ownership or workspace permission verification. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.
