CosmWasm affected by arithmetic overflows

Low severity GitHub Reviewed Published Apr 24, 2024 to the GitHub Advisory Database • Updated Jul 28, 2025

Package

cargo cosmwasm-std (Rust)

Affected versions

>= 1.3.0, < 1.4.4
>= 1.5.0, < 1.5.4
>= 2.0.0, < 2.0.2

Patched versions

1.4.4
1.5.4
2.0.2

Description

Some mathematical operations in cosmwasm-std use wrapping math instead of panicking on overflow for very big numbers. This can lead to wrong calculations in contracts that use these operations.

Affected functions:

  • Uint{256,512}::pow / Int{256,512}::pow
  • Int{256,512}::neg

Affected if overflow-checks = true is not set:

  • Uint{64,128}::pow / Int{64,128}::pow
  • Int{64,128}::neg

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
