Summary
Uncaught Exception in jsoup
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
Users may rate limit input parsing. Users should limit the size of inputs based on system resources. Users should implement thread watchdogs to cap and timeout parse runtimes.
Impact
What kind of vulnerability is it? Who is impacted?
Those using jsoup 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.
CVE-2021-37714 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.14.2); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2021-37714? CVE-2021-37714 is a high-severity security vulnerability in org.jsoup:jsoup (maven), affecting versions < 1.14.2. It is fixed in 1.14.2.
- How severe is CVE-2021-37714? CVE-2021-37714 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.jsoup:jsoup are affected by CVE-2021-37714? org.jsoup:jsoup (maven) versions < 1.14.2 is affected.
- Is there a fix for CVE-2021-37714? Yes. CVE-2021-37714 is fixed in 1.14.2. Upgrade to this version or later.
- Is CVE-2021-37714 exploitable, and should I be worried? Whether CVE-2021-37714 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2021-37714 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2021-37714? Upgrade
org.jsoup:jsoupto 1.14.2 or later.
