From Prompt Injection to Web Exploitation: Revisiting Classic Vulnerabilities in LLM-Integrated Applications
A research paper by Spiros Tsigkopoulos and Christoforos Ntantogian introduces "LLM-mediated web attacks," a class where attacker-controlled input is transformed by an LLM-integrated application and then reaches traditional web-app sinks, systematized as LLM2X variants (LLM2SQLi, LLM2XSS, LLM2SSTI, LLM2CommandInjection, LLM2IDOR, LLM2CSRF, LLM2XXE, LLM2SSRF). The authors implement TicketOracle, a Flask-based LLM-integrated app, to evaluate LLM2SSRF across five scenarios and seven LLMs, finding substantial model-specific variation in susceptibility.

Exposed by Design: A Dynamic Security Assessment of Internet-Facing MCP Servers at Scale
An arXiv paper by Nicolás Padilla presents the first dynamic behavioral security assessment of internet-facing Model Context Protocol (MCP) servers, discovering over 21,000 instances, confirming 640 production servers, and dynamically auditing 414 using Corvus, a purpose-built framework with 34 test modules across 10 MCP-specific vulnerability classes. The study uncovered 68 reportable vulnerabilities including SQL injection, SSRF targeting cloud metadata, prompt template injection, and path traversal, and found 91.8% of audited servers lack OAuth authentication and 687 tool instances exposing shell execution without access controls. The authors release Corvus as an open-source MCP security evaluation framework. Details →First reported equixly.com
How an AI agent talked itself into an XXE — and was right
Equixly describes how its autonomous AI agent, starting only from an OpenAPI specification and low-privileged credentials, identified an XML External Entity (XXE) injection in the chat layer of a collaboration platform, flagged an ordinary-looking JSON message-forward field as an XML sink, and confirmed it out-of-band. The agent then chained the flaw to local file reads and server-side request forgery to exfiltrate a cleartext database credential during a grey-box assessment. Details →How the wire is made
Poll & cluster
Internet is crawled for AI security news and near-duplicate coverage is embedded and grouped into durable items.
Curate
AI Agent filters for agentic-AI relevance, classifies and tags each item, scores severity for threats, and writes the summary.
Every item here is one machine-curated intelligence object, not a headline.
