CVE-2026-53937 MCP Kotlin SDK's unbounded line buffer in StdioServerTransport/StdioClientTransport leads to memory exhaustion (DoS)
MCP Kotlin SDK is the Kotlin Multiplatform software development kit for the Model Context Protocol. In versions 0.7.0 through 0.12.0, ReadBuffer.append in kotlin-sdk-core/src/commonMain/kotlin/io/modelcontextprotocol/kotlin/sdk/shared/ReadBuffer.kt writes every chunk of bytes received from the...

CVE-2026-53937
CVE-2026-53937 affects the MCP Kotlin SDK (versions 0.7.0–0.12.0 ). The root cause is an unbounded kotlinx.io.Buffer in ReadBuffer.append, which grows indefinitely when the stdio transport receives a byte stream without a terminating newline. The issue is amplified by StdioServerTransport and Std...

Security Bulletin: Langflow is vulnerable to arbitrary code execution due to multiple incomplete code security controls and missing execution guards
Summary Langflow uses a code security scanner and component-level execution policies to restrict server-side code execution to authorized users and contexts. The agentic assistant code scanner employs an incomplete denylist omitting process-spawning primitives and contains a logic error where...
Security Bulletin: Langflow is vulnerable to authentication bypass and insufficient session expiration
Summary Langflow provides API key-based authentication for programmatic access to flow execution and MCP endpoints. The MCP HTTP API credential resolvers do not apply the same AUTOLOGIN API-key guard that all standard authenticated endpoints enforce; when Langflow is in its default AUTOLOGIN...
