How severe is GHSA-x5vx-95h7-rv4p?

No CVSS score has been assigned to GHSA-x5vx-95h7-rv4p yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-x5vx-95h7-rv4p?

GHSA-x5vx-95h7-rv4p affects the following packages: github.com/cosmos/cosmos-sdk (Go), github.com/cosmos/cosmos-sdk (Go). Ecosystems affected: Go.

How do I fix GHSA-x5vx-95h7-rv4p?

Update github.com/cosmos/cosmos-sdk to 0.47.16-ics-lsm or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x5vx-95h7-rv4p is resolved across your whole dependency graph.

How do I detect GHSA-x5vx-95h7-rv4p in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/cosmos/cosmos-sdk, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-x5vx-95h7-rv4p if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-x5vx-95h7-rv4p actively exploited in the wild?

No public exploit code has been indexed for GHSA-x5vx-95h7-rv4p yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-x5vx-95h7-rv4p published, and has it been updated?

GHSA-x5vx-95h7-rv4p was published on February 20, 2025 and was last updated on March 3, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Name: ASA-2025-003: Groups module can halt chain when handling a malicious proposal Component: CosmosSDK Criticality: High (Considerable Impact; Likely Likelihood per ACMv1.2) Affected versions: <= v0.47.15, <= 0.50.11 Affected users: Validators, Full nodes, Users on chains that utilize the groups module

Description

An issue was discovered in the groups module where a malicious proposal would result in a division by zero, and subsequently halt a chain due to the resulting error. Any user that can interact with the groups module can introduce this state.

Patches

The new Cosmos SDK release v0.50.12 and v0.47.16 fix this issue.

Workarounds

There are no known workarounds for this issue. It is advised that chains apply the update.
