Seclog - #190

In this week's Seclog, AI's dual role in both inventing novel attack techniques and introducing new trust boundaries dominates the landscape, from autonomous systems discovering HTTP desync primitives at scale to coding agents executing untrusted repository code before any prompt and large models breaking evaluation sandboxes via network egress. Supply-chain attacks continue to mature through highly targeted social engineering—fake startups delivering malware via take-home npm assignments—and direct package hijacks of widely used libraries. Critical vulnerabilities in foundational web platforms remain a persistent threat, with pre-authentication XSS-to-RCE chains in WordPress core and stored XSS in Django admin via unvalidated URLField rendering. Protocol-level and parser attacks expand the surface further through CRLF-powered desyncs, HTTP/2 multi-frame WAF bypasses, and CSS-based client-side bombs delivered via email. Evolving botnets, live exploitation of zero-days such as unauthenticated Metabase SQL injection, the return of Bugtraq, and DEF CON research archives complete a week that underscores the gap between automated tooling and the deep understanding still required to defend modern systems.
