Summary
abomonation transmutes &T to and from &[u8] without sufficient constraints
This transmute is at the core of the abomonation crates. It's so easy to use it to violate alignment requirements that no test in the crate's test suite passes under miri.
The use of this transmute in serialization/deserialization also incorrectly assumes that the layout of a repr(Rust) type is stable.
This transmute can also disclose both the contents of padding bytes which may be an information leak and the contents of pointers, which may be used to defeat ASLR.
Impact

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-HFXP-P695-629X? GHSA-HFXP-P695-629X is a high-severity security vulnerability in abomonation (rust), affecting versions <= 0.7.3. No fixed version is listed yet.
- Which versions of abomonation are affected by GHSA-HFXP-P695-629X? abomonation (rust) versions <= 0.7.3 is affected.
- Is there a fix for GHSA-HFXP-P695-629X? No fixed version is listed for GHSA-HFXP-P695-629X yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-HFXP-P695-629X exploitable, and should I be worried? Whether GHSA-HFXP-P695-629X 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-HFXP-P695-629X 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.
