Hi,

The following vulnerability was published for jsoup.

CVE-2021-37714[0]:
| jsoup is a Java library for working with HTML. Those using jsoup
| versions prior to 1.14.2 to parse untrusted HTML or XML may be
| vulnerable to DOS attacks. If the parser is run on user supplied
| input, an attacker may supply content that causes the parser to get
| stuck (loop indefinitely until cancelled), to complete more slowly
| than usual, or to throw an unexpected exception. This effect may
| support a denial of service attack. The issue is patched in version
| 1.14.2. There are a few available workarounds. Users may rate limit
| input parsing, limit the size of inputs based on system resources,
| and/or implement thread watchdogs to cap and timeout parse runtimes.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
