CVE-2026-55520: Python Wildcard To Regex Redos
Translating wildcard patterns into regular expressions by mapping '*' to '.*?' or '.*' can lead to catastrophic backtracking (ReDoS) when evaluated against untrusted or complex inputs. Use non-regex string scanning (such as str.find/split) or a linear-time pattern matcher instead.
