By crafting a very-very-long user-agent string with specific pattern, an attacker can turn the script to get stuck processing for a very long time which results in a denial of service (DoS) condition. ### Affected Versions: From version `0.7.30` to before versions `0.7.33` / `1.0.33`. ### Patches: A patch has been released to remove the vulnerable regular expression, update to version `0.7.33` / `1.0.33` or later. ### References: [Regular expression Denial of Service - ReDoS](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_-_ReDoS) ### Credits: Thanks to @Snyk who first reported the issue.
