What is GHSA-7225-M954-23V7?

GHSA-7225-M954-23V7 is a high-severity integer overflow or wraparound vulnerability in cosmossdk.io/math (go), affecting versions <= 1.3.0. It is fixed in 1.4.0. An arithmetic operation produces a value that exceeds the integer type's maximum, causing it to wrap to an unexpected small value.

Which versions of cosmossdk.io/math are affected by GHSA-7225-M954-23V7?

cosmossdk.io/math (go) versions <= 1.3.0 is affected.

Is there a fix for GHSA-7225-M954-23V7?

Yes. GHSA-7225-M954-23V7 is fixed in 1.4.0. Upgrade to this version or later.

Is GHSA-7225-M954-23V7 exploitable, and should I be worried?

Whether GHSA-7225-M954-23V7 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-7225-M954-23V7 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-7225-M954-23V7?

Upgrade cosmossdk.io/math to 1.4.0 or later.

Impact

The bit-length in sdk.Int and sdk.Dec are not aligned, which may present a possible panic condition when interacting with Dec types in an Int context. This issue was resolved by aligning the max size between the data types in the cosmossdk.io/math package.

This issue impacts consumers of the cosmossdk.io/math, which includes popular modules including IBC-Go and tokenfactory (permissionless). If your chain interacts with APIs in the cosmossdk.io/math package, or utilizes a module that consumes this library, it is advised to update to the latest version at the time of the patch release by updating your project's go.mod dependency for cosmossdk.io/math.

The patch can be applied without a hard-fork, and with a version bump in a chain's go.mod file like the following:

An arithmetic operation produces a value that exceeds the integer type's maximum, causing it to wrap to an unexpected small value. Typical impact: incorrect size calculations leading to heap overflows or logic errors.

Affected versions

cosmossdk.io/math (<= 1.3.0)

Security releases

cosmossdk.io/math → 1.4.0 (go)

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.

Remediation advice

The new release of cosmossdk.io/math v1.4.0 resolves this issue. Chains that utilize the cosmossdk.io/math library or modules that utilize the cosmossdk.io/math library should update to avoid this condition.
