182 high-severity fixes in this history; regressions here are high-impact.

Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Bypasses in the experimental Permission Model frequently occur due to incomplete path canonicalization or type confusion where paths passed as Uint8Arrays or Buffers bypass checks entirely. Ensuring strict string/Buffer conversions and path normalization prevents unauthorized system access.

Denial of Service: The HTTP/2 session and stream implementation has historically been vulnerable to memory exhaustion and assertion crashes from floods of empty DATA frames, settings frame floods, and invalid window update paths (Reset Flood).

Command Injection: Spawning child processes with user-controlled arguments, especially on Windows when executing batch (.bat/.cmd) files, can lead to silent argument truncation or shell bypasses if not rigorously validated.
