From 3.0.0 until 3.10.1, the selector lexer matchRegexPattern closure in (*Tokenizer).parseCurRune in selector/lexer/tokenize.go loops while tokenizing an unterminated regex literal such as r/ because peekRuneEqual returns false after the end of input, allowing attacker-controlled selector strings to consume CPU indefinitely. This issue is fixed in version 3.10.1."

Desde la versión 3.0.0 hasta la 3.10.1, el cierre matchRegexPattern del analizador léxico de selectores en (Tokenizer).parseCurRune en selector/lexer/tokenize.go entra en un bucle al tokenizar un literal de expresión regular no terminado como r/ porque peekRuneEqual devuelve falso después del final de la entrada, permitiendo que cadenas de selectores controladas por el atacante consuman CPU indefinidamente. Este problema está solucionado en la versión 3.10.1."
