description

HarnessRouter versions before 0.37.16 may serve workspace artifacts with active content from the console origin without a sandbox policy. An attacker who can influence files produced in a session workspace may cause script to run with an operator's console session when that operator opens the artifact.

mitigation

Upgrade the HarnessRouter Docker image to version 0.37.16 or later. Until upgraded, prevent untrusted or agent-produced HTML and SVG artifacts from being opened through the console.

fixed in 0.37.16
