Introduction
Silent data corruption in production is among the most challenging issues for any engineering team to diagnose and remediate. In high-concurrency Go applications, a subtle race condition in the database/sql package can cause query results to be silently overwritten or mixed, leading to unpredictable application behavior and data integrity problems. CVE-2025-47907 is a concrete example of this risk, affecting a core component of the Go ecosystem used by thousands of organizations worldwide.
Go, developed by Google, is a foundational language for cloud infrastructure, backend services, and distributed systems. Its database/sql package is the de facto standard for database access in Go applications, and is used by nearly all major Go database drivers. This makes the impact of CVE-2025-47907 broad and significant for any team relying on Go for concurrent database workloads.
Technical Information
CVE-2025-47907 is a race condition vulnerability in Go's standard library, specifically in the database/sql package. The issue arises when a database query is cancelled via context (for example, due to a timeout or explicit cancellation) during a call to the Scan method on a Rows object, while other queries are being executed in parallel.
When this scenario occurs, the cleanup routines triggered by context cancellation can interfere with the ongoing scanning of results. Because database/sql and most drivers use shared connection resources and internal buffer management, a cancelled query can cause the result buffers to be prematurely released or reassigned. As a result, the Scan call may return data from another concurrent query or produce an error, rather than the expected results for the original query.
This vulnerability is not limited to a single database driver. It affects most drivers that implement the database/sql interface, including those for MySQL and PostgreSQL. The root cause is the lack of proper synchronization between context cancellation cleanup and the result scanning logic. The race condition is most likely to manifest in applications that:
- Perform many concurrent queries
- Use context cancellation for timeouts or user interrupts
- Share database connections across goroutines
No public code snippet is available for the vulnerable section. However, the Go issue tracker and related advisories provide detailed descriptions of the race window and its impact.
Patch Information
In response to the critical vulnerability identified in the Gemini Command Line Interface (CLI), Google has released version 0.1.14, which implements several key security enhancements to mitigate the risk of prompt injection attacks.
Enhanced Command Execution Approval
Previously, Gemini CLI allowed users to whitelist certain commands for execution without repeated prompts. However, this mechanism could be exploited by attackers to execute malicious commands under the guise of trusted ones. The updated version introduces a more robust approval process:
- Explicit User Confirmation: For any command execution, especially those involving external binaries or scripts, Gemini CLI now requires explicit user confirmation, regardless of prior whitelisting. This ensures that users are aware of and consent to each command executed by the tool.
Improved Command Visibility
To prevent the execution of hidden or obfuscated commands, the update enhances the visibility of commands being executed:
- Transparent Command Display: All commands initiated by Gemini CLI are now displayed in the terminal interface, making it clear to users what actions are being performed. This transparency helps users identify any unexpected or unauthorized commands.
Strengthened Input Validation
The update also addresses the issue of inadequate input validation that previously allowed malicious commands to be executed without detection:
- Sanitization of Inputs: Gemini CLI now includes enhanced input validation mechanisms that sanitize and verify all inputs before execution. This prevents the processing of inputs that could be manipulated to execute unintended commands.
Sandboxing Recommendations
To further isolate the execution environment and protect the host system, Google recommends utilizing sandboxing techniques:
- Integration with Sandboxing Tools: Gemini CLI offers integrations with Docker, Podman, and macOS Seatbelt, allowing users to run the tool within a controlled environment. This containment strategy limits the potential impact of any security breaches.
By implementing these measures, the updated Gemini CLI significantly reduces the risk of prompt injection attacks and enhances the overall security posture of the tool.

Affected Systems and Versions
CVE-2025-47907 affects Go's database/sql package in all versions prior to 1.24.6 and 1.23.12. Any Go application using the standard database/sql package for concurrent queries with context cancellation is potentially vulnerable. Most database drivers that rely on the standard package are impacted, including but not limited to MySQL and PostgreSQL drivers.
- Affected: Go 1.24.5 and earlier, Go 1.23.11 and earlier
- Fixed: Go 1.24.6 and Go 1.23.12
Vendor Security History
Go has previously addressed race conditions and resource management issues in its standard library, including the database/sql package. The Go team is recognized for prompt patching and clear advisories. For CVE-2025-47907, the vulnerability was reported by Spike Curtis from Coder and addressed with coordinated releases and public advisories. The Go project maintains a strong security response track record.
