Summary

Flowsint: Stored XSS on map node marker in map page

Details

Flowsint is an open-source OSINT graph exploration tool designed for cybersecurity investigation, transparency, and verification. Prior to 1.2.3, a remote attacker can create a map node with a malicious label that contains arbitrary HTML. When the map tab is selected and a map node marker is selected, it will render the arbitrary HTML, potentially triggering stored XSS. This vulnerability is fixed in 1.2.3.
