CVE-2026-14380 HMBRAND CVE debrief

Who should care

Users of DBI versions before 1.650 for Perl should review and update their installations to prevent potential code injection attacks. This includes operators, platform administrators, vulnerability management teams, and security teams who need to assess the risk and apply mitigations. Affected deployments may exist in managed environments, and owners should be assigned for follow-up. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified.

Technical summary

DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile. When a string is assigned to a DBI handle's Profile attribute, DBI splits it into path, package, and arguments, and interpolates the package part in a string eval with no validation of the package name. Any caller-influenced value that reaches the Profile attribute is therefore arbitrary Perl code execution, including calls to run system commands. The Profile attribute can be set from three different sources that can carry untrusted data: the DBI_PROFILE environment variable, a direct attribute assignment, and a DSN driver-attribute clause dbi:Driver(Profile=>SPEC):db.

Defensive priority

High priority should be given to updating DBI to version 1.650 or later to prevent code injection attacks. Additional defensive measures include reviewing and validating inputs to the Profile attribute, monitoring for suspicious activity related to DBI usage, and applying compensating controls for exposed systems.

Recommended defensive actions

• Update DBI to version 1.650 or later
• Review and validate inputs to the Profile attribute
• Monitor for suspicious activity related to DBI usage
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record was published on 2026-07-07T23:16:53.963Z and has not been modified since then. The NVD entry is currently Received. There is limited information available about the CVE, and defenders should verify the affected scope and severity with the vendor. The DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile. The Profile attribute can be set from three different sources that can carry untrusted data: the DBI_PROFILE environment variable, a direct attribute assignment, and a DSN driver-attribute clause dbi:Driver(Profile=>SPEC):db. An attacker controlling any of those inputs runs arbitrary Perl in the host process.
