go-redis is the official Redis client library for the Go programming language. Prior to 9.5.5, 9.6.3, and 9.7.3, go-redis potentially responds out of order when `CLIENT SETINFO` times out during connection establishment. This can happen when the client is configured to transmit its identity, there are network connectivity issues, or the client was configured with aggressive timeouts. The problem occurs for multiple use cases. For sticky connections, you receive persistent out-of-order responses for the lifetime of the connection. All commands in the pipeline receive incorrect responses. When used with the default ConnPool once a connection is returned after use with ConnPool#Put the read buffer will be checked and the connection will be marked as bad due to the unread data. This means that at most one out-of-order response before the connection is discarded. This issue is fixed in 9.5.5, 9.6.3, and 9.7.3. You can prevent the vulnerability by setting the flag DisableIndentity to true when constructing the client instance.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 3.7, indicating it can be exploited remotely over the network but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts limited integrity, for affected systems.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
