Summary
Denial of Service in @commercial/subtext
Versions of @commercial/subtext prior to 5.1.1 are vulnerable to Denial of Service (DoS). The package fails to enforce the maxBytes configuration for payloads with chunked encoding that are written to the file system. This allows attackers to send requests with arbitrary payload sizes, which may exhaust system resources leading to Denial of Service.
Impact
Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

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 GHSA-FVWR-H9XH-M6WC? GHSA-FVWR-H9XH-M6WC is a high-severity uncontrolled resource consumption vulnerability in @commercial/subtext (npm), affecting versions < 5.1.1. It is fixed in 5.1.1. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.
- Which versions of @commercial/subtext are affected by GHSA-FVWR-H9XH-M6WC? @commercial/subtext (npm) versions < 5.1.1 is affected.
- Is there a fix for GHSA-FVWR-H9XH-M6WC? Yes. GHSA-FVWR-H9XH-M6WC is fixed in 5.1.1. Upgrade to this version or later.
- Is GHSA-FVWR-H9XH-M6WC exploitable, and should I be worried? Whether GHSA-FVWR-H9XH-M6WC 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 GHSA-FVWR-H9XH-M6WC 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.
