    Letting users trust their own MCP clients, without opening a phishing hole

    Judge 2 Detailed, well-sourced engineering write-up on OAuth redirect URI trust for MCP servers, security-focused with concrete mitigations; partly a product description, so promotional leaning is moderate and breadth is niche-to-large.

  38. No. 48Score 0.68

    Let's Talk About Black October

    Judge 2 Detailed, practical security write-up on JVM trust-store exposure from the eMudhra CA compromise with concrete checks; some vendor promotion and overlap with recent coverage tempers novelty and substantiation.

  39. No. 49Score 0.67

    An AppArmor Stacking Incident Misdiagnosed as a Network Failure

    Judge 2 Detailed, well-evidenced debugging writeup of a real kernel/AppArmor regression affecting containerized databases; practically useful to infra builders, though narrow in audience and mostly about one homelab's incident.
