Denial Of Service (DoS)

github.com/cosmos/cosmos-sdk is vulnerable to Denial of Service. The vulnerability is due to improper proposal handling due to malicious proposals triggering errors in the module's end blocker, potentially resulting in a chain halt...

GHSA-H2RP-8VPX-Q9R4 cheqd-node Security patch for upstream vulnerabilities in IBC-Go (ISA-2025-001) and Cosmos SDK (ISA-2025-002)

Description There have been two upstream security advisories and associated patches published under ISA-2025-001 and ISA-2025-002. ISA-2025-001 affects the IBC-Go package., where non-deterministic JSON unmarshalling of IBC Acknowledgements can result in a chain halt. ISA-2025-002 affects the Cosm...

IBC-Go: Non-deterministic JSON Unmarshalling of IBC Acknowledgement can result in a chain halt

Name: ISA-2025-001: Non-deterministic JSON Unmarshalling of IBC Acknowledgement can result in a chain halt Component: IBC-Go Criticality: High Considerable Impact; Likely Likelihood per ACMv1.2 Affected versions: IBC-Go = v7; Earlier IBC-Go versions MAY also be affected. Affected users: Validator...

GHSA-33CR-M232-XQCH cheqd-node affected by Non-deterministic JSON Unmarshalling of IBC Acknowledgement

Description An issue was discovered in IBC-Go's deserialization of acknowledgements that results in non-deterministic behavior which can halt a chain. Any user that can open an IBC channel can introduce this state to the chain. This an upstream dependency used in cheqd-node, rather than a custom...
