Summary
cggmp21 vulnerable to ambiguous challenge derivation
Challenge derivation in non-interactive ZK proofs was ambiguous and that could lead to security vulnerability (however, it's unknown if it could be exploited).
Impact
The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES. Typical impact: compromised confidentiality or integrity of protected data.
Affected versions
Security releases
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-RM66-9GH4-4GP8? GHSA-RM66-9GH4-4GP8 is a low-severity use of a broken or risky cryptographic algorithm vulnerability in cggmp21 (rust), affecting versions < 0.4.0. It is fixed in 0.4.0. The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES.
- Which versions of cggmp21 are affected by GHSA-RM66-9GH4-4GP8? cggmp21 (rust) versions < 0.4.0 is affected.
- Is there a fix for GHSA-RM66-9GH4-4GP8? Yes. GHSA-RM66-9GH4-4GP8 is fixed in 0.4.0. Upgrade to this version or later.
- Is GHSA-RM66-9GH4-4GP8 exploitable, and should I be worried? Whether GHSA-RM66-9GH4-4GP8 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-RM66-9GH4-4GP8 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 GHSA-RM66-9GH4-4GP8? Upgrade
cggmp21to 0.4.0 or later.
