CVE-2026-42157 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in Flowsint, an open-source OSINT graph exploration tool, prior to version 1.2.3. The issue allows remote attackers to inject arbitrary HTML into map nodes. When the map tab is accessed and a node marker is clicked, the injected HTML is rendered, potentially executing malicious scripts. This vulnerability arises because the application uses innerHTML to display node labels, enabling HTML injection.
Users are advised to update Flowsint to version 1.2.3 or later, where this vulnerability has been fixed.
