EUVD-2026-45234Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Attacker needs local access and low privileges to influence the JDBC URL (AV:L, PR:L); injection is straightforward (AC:L) and code execution yields full C/I/A impact.
Primary rating from Vendor (ibm).

IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.4 is vulnerable to remote code execution when jdbc url is under user control.
AnalysisAI
Code injection leading to remote code execution affects IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 when an attacker can influence the JDBC connection URL passed to the driver. An attacker who controls the JDBC URL (typically via an application that builds connection strings from user input) can inject malicious properties or references that cause arbitrary code to execute in the context of the connecting application/driver host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker control, or be able to influence, the JDBC connection URL that is handed to the IBM Db2 driver - for example an application, admin console, or configuration path that builds connection strings from user-supplied values. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 3.1 score is 7.8 (High) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H - local attack vector, low complexity, low privileges required, no user interaction, and full confidentiality/integrity/availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An application allows a user or lower-privileged operator to influence part of a Db2 JDBC connection string (for example a data-source parameter or a 'test connection' feature). The attacker supplies a crafted JDBC URL containing malicious properties that the Db2 driver resolves at connect time, causing arbitrary code to execute with the privileges of the application process. … |
| Remediation | Patch available per vendor advisory - apply the IBM-provided fix pack or iFix documented at https://www.ibm.com/support/pages/node/7279479 for the appropriate Db2 line (11.5.x or 12.1.x); the exact fixed version was not enumerated in the provided data, so consult that advisory for the precise level. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all Db2 deployments running versions 11.5.0-11.5.9 or 12.1.0-12.1.4 and audit which applications construct JDBC connection strings from external input, application configuration files, or admin panels. …
