AI-Generated

The vulnerability affects Dasel versions 3.0.0 to 3.10.1, where an attacker can exploit an unterminated regex literal in selector strings, leading to a denial-of-service condition by causing excessive CPU consumption. Organizations using Dasel for data manipulation should prioritize upgrading to version 3.10.1 to mitigate this risk. This issue is particularly relevant for environments where Dasel is integrated into automated workflows or processing pipelines.

Original NVD Description

Dasel is a command-line tool and library for querying, modifying, and transforming data structures. 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.
