jackson-databind: jackson-databind: Arbitrary code execution via PolymorphicTypeValidator bypass

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass the PolymorphicTypeValidator PTV when polymorphic typing is enabled and a type identifier contains generic parameters. By crafting a malicious type ID, an attacker can place a denied class as a generic typ...

CVE-2026-75844 ArcadeDB before 26.8.1 SSRF via IMPORT DATABASE validator bypass

ArcadeDB versions before 26.8.1 contain a server-side request forgery vulnerability in the IMPORT DATABASE command where the security validator resolves and checks hostnames but the subsequent connection re-resolves the raw URL and follows redirects. Authenticated attackers can bypass the validat...

CVE-2026-69264 Flowise: RCE via CSVAgent csvFile data URI base64 segment is interpolated into Python source without validation

Prior to 3.1.3, Flowise CSVAgent interpolates an attacker-controlled segment of the csvFile data URI directly into a Python source-code template that is then executed by Pyodide. Because Pyodide is loaded with the default js bridge to globalThis, which on Node.js exposes eval and dynamic import,...

Security Bulletin: MCP Server Configuration Validator Bypass via File Upload API

Summary A validation bypass vulnerability existed in the File Manager API that could allow an authenticated attacker to upload malicious MCP server configurations. The file upload endpoint accepted mcpservers.json files without invoking the MCPServerConfig validator, while the structured MCP API...
