CVE-2026-4918 is a stored cross-site scripting vulnerability affecting IBM Guardium Data Protection version 12.1 that permits administrative users to inject arbitrary JavaScript code into the Web UI, potentially compromising the integrity of the application and exposing user credentials within authenticated sessions. The vulnerability carries a CVSS 3.1 score of 5.5 (Medium), reflecting a network-accessible attack surface with low complexity but requiring high-level administrative privileges to execute. While the attack has low exploitability potential given the administrative access requirement, it presents moderate risk through scope changes and potential credential disclosure. There is currently no evidence of active exploitation in the wild, no public exploit code availability, and the vulnerability maintains minimal community attention as indicated by its inactive status on public vulnerability tracking lists and exceptionally low EPSS score.
