Free key for authorized security research.2026-07-15https://vulntel.com/pull-vs-push-mcphttps://vulntel.com/pull-vs-push-mcpWhy an MCP server can't make an agent follow a multi-step loop by nudging it from tool responses, why 'prompt injection for good' both breaks trust and backfires, and why the push you actually want turns out to be persistent state, not clever phrasing.2026-07-14https://vulntel.com/catch-hallucinated-cveshttps://vulntel.com/catch-hallucinated-cvesAI agents invent CVE IDs that do not exist, assign the wrong severity, and attribute a bug to the wrong product. Here is how to fact-check every CVE claim against a ground-truth corpus (NVD + OSV + GHSA + CISA KEV) in one call, with real refuted examples.2026-07-14https://vulntel.com/ai-security-agent-bottleneckhttps://vulntel.com/ai-security-agent-bottleneckField notes from pointing AI agents at real bug-bounty targets: the ceiling is an environment boundary, not model quality; the highest-value memory is your failures, which no CVE database contains; and why a confident claim is a hypothesis to falsify, not a result.2026-07-14https://vulntel.com/vulnerability-mechanism-transferhttps://vulntel.com/vulnerability-mechanism-transferA data analysis of ~10,000 disclosed HackerOne reports distilled into product-agnostic 'mechanism cards' and embedded: the median vulnerability mechanic has already been independently filed against 4 different products, a third against 11+, and 27% of decade-old mechanics still recruit a brand-new product every 18 months. Vulnerability mechanisms are reused - and keep spreading - far more than the product-centric (one-CVE-per-product) view suggests. With method, numbers, and limitations.2026-06-29https://vulntel.com/predicting-exploitationhttps://vulntel.com/predicting-exploitationA data analysis of 330k CVEs with CISA KEV as ground truth: EPSS vs CVSS, the exploit-PoC reference as a near-perfect filter, exploitation magnets by CWE and ecosystem, and how time-to-exploit collapsed to days.2026-06-05https://vulntel.com/llm-bug-hunting-experimentshttps://vulntel.com/llm-bug-hunting-experimentsWe tested whether a 330k-CVE corpus turns an LLM into a better vulnerability researcher, mechanism pattern-cards, invariant reconstruction, cheap-model uplift, change-history prediction, and vulnerable-vs-patched discrimination. Honest results, including the failures.2026-06-05https://vulntel.com/vulnerability-prioritizationhttps://vulntel.com/vulnerability-prioritizationWhy patching by CVSS fails, what a defensible P1–P4 priority model looks like, and how CISA's SSVC reconstructs the KEV exploited-list at 99.9%, with worked examples (BlackLotus, the xz backdoor, Log4Shell).2026-06-05
