CVE-2025-47907: High Vulnerability in Golang Go

CVE-2025-47907 is a high-severity vulnerability affecting the Go programming language developed by Golang. This vulnerability allows for unexpected behavior during the execution of queries when one query is cancelled while another is concurrently processed. Specifically, cancelling a query by cancelling the context passed to the query methods during a call to the Scan method can lead to race conditions, resulting in overwritten results or errors. With a CVSS score of 7.0, this vulnerability poses a significant risk to applications relying on concurrent query execution.

Risk to organizations includes potential data integrity issues and unexpected application behavior, particularly in environments where multiple queries are processed simultaneously. Given the nature of the vulnerability, attackers may leverage this flaw to manipulate the data returned by queries, which could impact decision-making processes or lead to unauthorized data exposure.

Organizations should prioritize patching immediately. The vendor has released patches to address this issue, and it is crucial for organizations using affected versions of Go to apply these updates as soon as possible to mitigate the risk of exploitation.

The vulnerability was published on August 7, 2025, and is currently not listed in the Known Exploited Vulnerabilities (KEV) catalog. This highlights an immediate need for organizations to stay informed about vulnerabilities affecting their technology stack.

Organizations utilizing Golang's Go should not only apply the recommended patches but also consider implementing additional security measures to further protect against potential vulnerabilities in their applications.

Vulnerability Details

The official description of CVE-2025-47907 states: 'Cancelling a query (e.g., by cancelling the context passed to one of the query methods) during a call to the Scan method of the returned Rows can result in unexpected results if other queries are being made in parallel. This can result in a race condition that may overwrite the expected results with those of another query, causing the call to Scan to return either unexpected results from the other query or an error.'

This vulnerability is classified under CWE-362, which pertains to race conditions. The CVSS score for this vulnerability is 7.0, indicating a high severity level. The attack vector is classified as NETWORK, with a high attack complexity and no privileges or user interaction required for exploitation.

Affected versions include all versions prior to the patches released in Go 1.24.6 and 1.23.12. Organizations should ensure they are running updated versions to avoid exposure to this vulnerability.

Technical Analysis

The root cause of CVE-2025-47907 stems from the way queries are handled concurrently in Go. When executing multiple queries simultaneously, if one query is cancelled, it can disrupt the expected flow of data, leading to race conditions. This behavior can be particularly problematic in applications that rely on the integrity of query results.

The attack vector is through network interactions where malicious actors may exploit the vulnerability by sending crafted requests that trigger the race condition. The complexity of this attack is classified as high due to the requirement for a specific timing and sequence of events to successfully manipulate the query outcomes.

The vulnerability requires no special privileges to exploit, and user interaction is not necessary. Its impact on confidentiality is high, as it may expose sensitive data from other queries. The integrity impact is low, meaning that while the results may be incorrect, they do not necessarily compromise data integrity. Availability is also impacted at a low level, as the erroneous results may affect application functionality.

Risk & Impact Analysis

The real-world risk associated with CVE-2025-47907 is significant, particularly for organizations that rely on concurrent database queries. The potential for unexpected results from cancelled queries poses a direct threat to the integrity of application data and decision-making processes. The blast radius of this vulnerability could extend to any application using the affected versions of Go, making it crucial for organizations to assess their exposure.

Given the high CVSS score and the potential for exploitation in a networked environment, organizations should prioritize remediation efforts based on this vulnerability's severity. The lack of confirmed exploitation in the wild does not diminish the need for immediate action. Organizations should implement robust testing and monitoring strategies to detect any anomalies that may arise from this vulnerability.

Organizations should also be aware of the implications of not addressing this vulnerability promptly. The risk of data loss, incorrect processing of information, and potential reputational damage can have long-lasting effects on business operations.

Exploitation Status

Affected Versions

The affected versions of Go include all versions prior to 1.24.6 and 1.23.12. Organizations should ensure they upgrade to these versions or later to mitigate the identified vulnerability.

Mitigation & Remediation

Organizations should immediately patch their systems to the latest versions of Go to remediate CVE-2025-47907. Specifically, upgrading to Go 1.24.6 or 1.23.12 is essential to address this vulnerability. If a patch cannot be applied immediately, organizations should consider implementing workarounds to minimize exposure, such as avoiding concurrent query executions where possible.

Additionally, organizations can implement configuration hardening practices to limit the impact of potential race conditions, such as ensuring that queries are executed in a controlled manner. Network controls should also be in place to monitor and restrict unauthorized access to databases.

For further guidance on security practices, organizations may refer to resources on penetration testing to validate their security posture and identify any other potential vulnerabilities.

Detection Guidance

To detect potential exploitation of CVE-2025-47907, organizations should monitor logs for unusual query behavior, such as unexpected results or error messages originating from concurrent query executions. Behavioral anomalies that deviate from normal operation should be investigated thoroughly.

Network signatures should also be established to identify patterns associated with attempts to exploit this vulnerability. Additionally, organizations should track any changes in system configurations or query performance that may indicate exploitation attempts.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2025-47907 lies in its representation of the challenges faced by developers in managing concurrent operations within applications. As more organizations adopt concurrent processing for efficiency, vulnerabilities of this nature may become increasingly prevalent.

Security teams must learn from this incident to enforce stricter testing and validation protocols for concurrent query handling. This includes rigorous testing of edge cases where queries may interact in unpredictable ways.

Strategic defensive takeaways include prioritizing security training for developers on concurrency issues and implementing comprehensive code reviews to identify potential race conditions before deployment. Organizations may also benefit from engaging in regular security assessments, such as application security assessments, to bolster their defenses against similar vulnerabilities.

Known Exploitation Timeline

This vulnerability has not been added to the Known Exploited Vulnerabilities (KEV) catalog, indicating that there are no known active exploitation attempts at this time.

EPSS Risk Context

The EPSS score for CVE-2025-47907 is approximately 0.00012, placing it in the 1.67 percentile. This low score suggests a minimal probability of exploitation in the near term, but it should not detract from the need for timely remediation efforts.
