A fix is available — apply it.

httpdbg before 2.2.1 fails to validate URL schemes in recorded HTTP request URLs rendered as clickable links in the web interface. Attackers controlling traffic recorded by httpdbg can supply javascript: scheme URLs that execute malicious scripts in the application origin when clicked, allowing access to captured request and response data including headers and tokens.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
