UnverifiedInboxWall may cause parser exceptions due to extremely malformed HTML, overly aggressive filtering may mistakenly delete legitimate content (such as stripping all <a> tags and losing links), new injection techniques may bypass the allowlist, and a crash of the MCP server process would leave the agent without sanitization capability.76% similarUnverifiedAnnotation declarations on MCP servers have no enforcement validation mechanism at the protocol level, creating a supply-chain trust problem where an attacker can publish a malicious server claiming to be read-only while performing arbitrary write operations.60% similarUnverifiedDisclosed MCP vulnerabilities include: argocd-mcp shipped with no authentication at all, Rill's OAuth flow allowed attackers to skip the user consent step, and prompt injection existed in the tool descriptions of multiple MCP servers.59% similarUnverifiedPrompt injection is a security vulnerability unique to LLM applications, where attackers can embed malicious instructions in tool results returned by an MCP server to manipulate agent behavior.59% similarUnverifiedThe attacker initially published a clean, normal MCP server to establish trust, and later planted malicious forwarding logic by adding a single line of code in a subsequent version update.59% similar
