Summary
Users vulnerable to unaligned read of const const c_char pointer
Affected versions dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior.
In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibility of working correctly in some architectures.
The crate is not currently maintained, so a patched version is not available.

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.

- Which versions of users are affected by GHSA-JCR6-4FRQ-9GJJ? users (rust) versions <= 0.11.0 is affected.
- Is there a fix for GHSA-JCR6-4FRQ-9GJJ? No fixed version is listed for GHSA-JCR6-4FRQ-9GJJ yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-JCR6-4FRQ-9GJJ exploitable, and should I be worried? Whether GHSA-JCR6-4FRQ-9GJJ 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-JCR6-4FRQ-9GJJ 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.
