Summary
Insecure Credential Storage in web3
All versions of web3 are vulnerable to Insecure Credential Storage. The package stores encrypted wallets in local storage and requires a password to load the wallet. Once the wallet is loaded, the private key is accessible via LocalStorage. Exploiting this vulnerability likely requires a Cross-Site Scripting vulnerability to access the private key.
Impact
GHSA-27V7-QHFV-RQQ8 has a CVSS score of 3.3 (Low). The vector is requires local access, low 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. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

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.
Remediation advice
No fix is currently available. Consider using an alternative module until a fix is made available.
Frequently Asked Questions
- What is GHSA-27V7-QHFV-RQQ8? GHSA-27V7-QHFV-RQQ8 is a low-severity security vulnerability in web3 (npm), affecting versions <= 1.5.2. No fixed version is listed yet.
- How severe is GHSA-27V7-QHFV-RQQ8? GHSA-27V7-QHFV-RQQ8 has a CVSS score of 3.3 (Low). 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 web3 are affected by GHSA-27V7-QHFV-RQQ8? web3 (npm) versions <= 1.5.2 is affected.
- Is there a fix for GHSA-27V7-QHFV-RQQ8? No fixed version is listed for GHSA-27V7-QHFV-RQQ8 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-27V7-QHFV-RQQ8 exploitable, and should I be worried? Whether GHSA-27V7-QHFV-RQQ8 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-27V7-QHFV-RQQ8 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.
