CVE-2026-60193 Overview
CVE-2026-60193 affects Oracle MySQL Connectors, specifically the Connector/Net component in supported versions 9.7.0 through 9.7.1. The flaw allows a low-privileged attacker with network access via multiple protocols to compromise MySQL Connectors. Successful exploitation can result in a full takeover of the Connector, and the scope change indicates impact extends beyond the vulnerable component to additional products. Oracle disclosed the issue in the July 2026 Critical Patch Update. The weakness is categorized under [CWE-284: Improper Access Control].
Critical Impact
Successful exploitation results in full takeover of MySQL Connectors with confidentiality, integrity, and availability impact, and scope change extending to additional connected products.
Affected Products
- Oracle MySQL Connectors 9.7.0
- Oracle MySQL Connectors 9.7.1
- Component: Connector/Net

Technical Details for CVE-2026-60193
Vulnerability Analysis
The vulnerability resides in the Connector/Net component of Oracle MySQL Connectors. Connector/Net is the ADO.NET driver used by .NET applications to communicate with MySQL servers. An attacker with low-privileged access on the network can exploit the flaw across multiple protocols to compromise the Connector. The scope change indicates that successful exploitation impacts resources beyond the vulnerable component itself, including applications that rely on the Connector for database access.
Exploitation is rated as difficult due to elevated attack complexity, but the resulting impact covers confidentiality, integrity, and availability. According to EPSS data from 2026-07-23, the probability of exploitation is 0.27% at the 18.869 percentile.
Root Cause
The underlying weakness is improper access control [CWE-284] in the Connector/Net component. Access decisions or trust boundaries within the driver do not adequately restrict what a low-privileged authenticated network actor can perform, enabling escalation into full Connector takeover.
Attack Vector
The attack is delivered over the network. The attacker must hold low-privilege credentials but does not require user interaction. Multiple protocols supported by Connector/Net can serve as the entry point. Because the scope changes, a compromised Connector can be leveraged to pivot into the .NET application layer and consumer processes that trust the driver.
No public exploit code or proof-of-concept has been observed. See the Oracle Security Alert July 2026 for vendor-provided details.
Detection Methods for CVE-2026-60193
Indicators of Compromise
- Unexpected process behavior in .NET applications that load MySql.Data.dll or related Connector/Net assemblies.
- Anomalous outbound MySQL protocol traffic originating from application servers, particularly connections to untrusted hosts.
- Unusual authentication attempts from low-privileged database accounts followed by lateral activity.
Detection Strategies
- Inventory all applications embedding Connector/Net 9.7.0 and 9.7.1 and correlate with runtime process telemetry.
- Monitor for unusual child processes spawned by .NET application hosts (w3wp.exe, dotnet.exe) that consume MySQL Connector libraries.
- Alert on MySQL client sessions that negotiate atypical protocol handshakes or authentication plugins on managed application servers.
Monitoring Recommendations
- Enable database audit logging for connection attempts, authentication plugin selection, and privilege usage from application service accounts.
- Collect and centralize .NET application logs to identify Connector/Net exceptions or crashes that may signal exploitation attempts.
- Baseline network flows between application servers and MySQL instances and alert on deviations in destination, port, or volume.
How to Mitigate CVE-2026-60193
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert July 2026 to all affected Connector/Net deployments.
- Identify all .NET applications shipping Connector/Net 9.7.0 or 9.7.1 and prioritize patch rollout to internet-adjacent systems first.
- Rotate credentials used by application service accounts that connect through the vulnerable Connector.
Patch Information
Oracle addressed CVE-2026-60193 in the July 2026 Critical Patch Update. Administrators should upgrade Connector/Net to a fixed release after 9.7.1 as listed in the Oracle Security Alert July 2026. Because Connector/Net is embedded within applications, patching typically requires redeploying application binaries with the updated NuGet package.
Workarounds
- Restrict network access to MySQL endpoints so only authorized application hosts can reach the database.
- Enforce least privilege on MySQL accounts used by Connector/Net, removing unnecessary schema and administrative privileges.
- Enable TLS for all Connector/Net sessions and require certificate validation to reduce exposure to protocol-level manipulation.
# Example NuGet upgrade command for a .NET application
dotnet remove package MySql.Data
dotnet add package MySql.Data --version <fixed-version-from-Oracle-CPU-July-2026>
dotnet build --configuration Release
