Summary
Details
If a user has access to documents that contain hidden fields or fields they do not have access to, the user could reverse-engineer those values via brute force.
Affected versions: < 1.7.0
Workarounds
If you are unable to update, you can write a beforeOperation hook to remove where queries that attempt to access hidden field data.
Detecting Compromise
Monitor your instance for brute-force style requests against your instance using where queries.
Impact
CVE-2023-30843 has a CVSS score of 7.4 (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 (1.7.0); 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.

Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2023-30843? CVE-2023-30843 is a high-severity security vulnerability in payload (npm), affecting versions < 1.7.0. It is fixed in 1.7.0.
- How severe is CVE-2023-30843? CVE-2023-30843 has a CVSS score of 7.4 (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 payload are affected by CVE-2023-30843? payload (npm) versions < 1.7.0 is affected.
- Is there a fix for CVE-2023-30843? Yes. CVE-2023-30843 is fixed in 1.7.0. Upgrade to this version or later.
- Is CVE-2023-30843 exploitable, and should I be worried? Whether CVE-2023-30843 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-2023-30843 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.
