Recurring patterns

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

Remote Code Execution: Unrestricted constant lookup using 'const_get' during Rouge syntax highlighter initialization allowed attackers to instantiate arbitrary Ruby classes, leading to remote code execution (CVE-2021-28834).

Arbitrary File Read: Processing arbitrary 'template' options inline within documents allowed attackers to perform unauthorized file disclosure or potentially execute embedded Ruby code via unsafe template parsing (CVE-2020-14001).
