Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Flaws in the core ACL evaluation logic, such as treating non-string identifiers improperly, performing loose character-by-character glob matching, or completely discarding default fallback rules when specific commands are configured, present a critical risk of complete command authorization bypass.
Auth Bypass: The IRC adapter historically validated commands using easily spoofed nicknames instead of the full hostmask, allowing unauthorized users to impersonate administrators. Failure to consistently enforce robust host-level patterns when evaluating permissions is a major risk on IRC networks.
Arbitrary Code Execution: Unsafe handling of standard input and backup restoration using raw python `eval` and `exec` commands allowed local or context-based arbitrary code execution before being replaced with safer abstract syntax tree parsing.
