xmldom has XML node injection through unvalidated processing instruction serialization

Summary The package allows attacker-controlled processing instruction data to be serialized into XML without validating or neutralizing the PI-closing sequence ?. As a result, an attacker can terminate the processing instruction early and inject arbitrary XML nodes into the serialized output. ---...

Attacking the MCP Trust Boundary

Every secure API draws a line between code and data. HTTP separates headers from bodies. SQL has prepared statements. Even email distinguishes the envelope from the message. The Model Context Protocol MCP, the fast-growing standard for connecting AI agents to external services, inherits that gap...
