140 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.
Command Injection: Improper argument escaping when spawning Windows batch (.bat/.cmd) files with shell options enabled directly leads to arbitrary command execution, bypassing Deno's sandbox restrictions. Variant fixes continually reinforce escaping around metacharacters and trailing characters.
Auth Bypass: Web Workers and dynamically imported modules have historically bypassed security permissions by failing to propagate the correct restricted worker permissions, falling back instead to root/parent configurations or unvalidated static paths.
Sandbox Escape: The Node.js SQLite integration introduced a path to bypass file system permission boundaries. Specifically, allowing the ATTACH DATABASE statement allowed malicious code to read/write arbitrary databases outside Deno's sandbox.
