Description
A stored DOM cross-site scripting issue exists in the Resource Locator component. The component passes the workflow-persisted
cachedResultUrl parameter to the window.open() function without validating the scheme. An attacker with privileges to create or edit workflows can include a malicious scheme, such as javascript:, in the cachedResultUrl variable. When a victim opens the crafted workflow and interacts with external links, the payload executes within the victim's browser.Recommendations
Update to version 1.123.64 or later.
Update to version 2.29.8 or later.
Update to version 2.30.1 or later.
Restrict workflow creation and editing permissions to fully trusted users only.
Audit existing workflows for unexpected
cachedResultUrl values containing non-HTTP(S) schemes.Exploit
Fix
