Summary
Triton VM Soundness Vulnerability due to Missing Constraint
The instruction sponge_absorb_mem Triton VM fails to verify that hashed values come from the claimed memory location. Malicious provers can substitute arbitrary data instead of actual memory contents.
Any application using instruction sponge_absorb_mem to hash memory data can be given a proof for a forged hash that doesn't correspond to the actual memory. This breaks the security of memory-based commitments.
The flaw was corrected in commits 17c7ba0a and ef9d9e72 by including the appropriate constraints.

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-VJF8-9FX6-MV6X? GHSA-VJF8-9FX6-MV6X is a medium-severity security vulnerability in triton-vm (rust), affecting versions >= 0.42.0-alpha.4, < 4.0.0. It is fixed in 4.0.0.
- Which versions of triton-vm are affected by GHSA-VJF8-9FX6-MV6X? triton-vm (rust) versions >= 0.42.0-alpha.4, < 4.0.0 is affected.
- Is there a fix for GHSA-VJF8-9FX6-MV6X? Yes. GHSA-VJF8-9FX6-MV6X is fixed in 4.0.0. Upgrade to this version or later.
- Is GHSA-VJF8-9FX6-MV6X exploitable, and should I be worried? Whether GHSA-VJF8-9FX6-MV6X 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-VJF8-9FX6-MV6X 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.
