Summary
Namada-apps allows Post-Genesis Validator Bypass
Workarounds
There are no workarounds and users are advised to upgrade.
Impact
Ledger crash. A user is able to initialize a post-genesis validator with a negative commission rate using the --force flag. If this validator gets into the consensus set, then when computing PoS inflation inside fn update_rewards_products_and_mint_inflation, an instance of mul_floor will cause the return of an Err, which causes finalize_block to error.

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.

This issue has been patched in apps version 1.1.0. The PoS validity predicate now enforces that the commission rate is not negative and any transaction that fails the check will be rejected, both for newly initialized validators and for commission rate change of an existing validator.
Frequently Asked Questions
- What is GHSA-2GW2-QGJG-XH6P? GHSA-2GW2-QGJG-XH6P is a critical-severity security vulnerability in namada-apps (rust), affecting versions = 1.0.0. It is fixed in 1.1.0.
- Which versions of namada-apps are affected by GHSA-2GW2-QGJG-XH6P? namada-apps (rust) versions = 1.0.0 is affected.
- Is there a fix for GHSA-2GW2-QGJG-XH6P? Yes. GHSA-2GW2-QGJG-XH6P is fixed in 1.1.0. Upgrade to this version or later.
- Is GHSA-2GW2-QGJG-XH6P exploitable, and should I be worried? Whether GHSA-2GW2-QGJG-XH6P 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-2GW2-QGJG-XH6P 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.
