What happened
Collection of GitHub Security Blog posts (late 2025–2026) covering open source vulnerability trends and defenses: reviewed advisories hit a four‑year low while malware advisories surged and CNA publishing increased; GitHub expanded application security using CodeQL plus AI‑powered detections across more languages and frameworks; GitHub Security Lab released the Taskflow Agent (an open‑source AI‑powered framework) to improve scanning and AI‑assisted triage for high‑impact issues (auth bypass, IDOR, token leaks, etc.); guidance on supply‑chain malware preparedness, continuous fuzzing limitations
