CVE-2026-55529 PraisonAI: Origin validation bypass in MCP HTTP Stream transport allows browser-mediated unauthenticated tool execution on local MCP server

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream validateorigin method accepts requestorigin.startswithallowed, so the attacker-controlled localhost.evil.example HTTP origin matches the localhost allowlist. Without an API key, a malicious webpage can submit...

PraisonAI has an origin validation bypass in MCP HTTP Stream transport that allows browser-mediated unauthenticated tool execution on local MCP server

Summary PraisonAI's MCP HTTP Stream transport uses an unsafe prefix match when validating the Origin header. The default localhost allowlist includes origins such as http://localhost, and the validation accepts any origin that starts with an allowed value. As a result, an attacker-controlled orig...

CVE-2026-79669 Ech0 before 4.4.3 Missing Authorization on System Logs

Ech0 before 4.4.3 lacks authorization checks on system log endpoints allowing any authenticated non-admin user to read and stream all server logs. Attackers can access historical logs and real-time log streams via GET /api/system/logs, GET /api/system/logs/stream, and WS /ws/system/logs to gather...

CVE-2026-68552

A flaw was found in Coturn. An unauthenticated remote client can send a specially crafted STUN message over TCP or TLS. This message, with a specific body-length field, causes an integer truncation overflow, leading to the desynchronization of the stream parser. Consequently, the attacking client...

CVE-2026-63639

A flaw was found in Valkey, a distributed key-value database. A remote attacker could exploit a use-after-free vulnerability in the RESTORE command. This occurs when a malformed data stream is processed during stream deserialization, causing a shared resource to be improperly managed. If...
