CVE-2026-55839

Descripción

Kestra is an open-source, event-driven orchestration platform. Prior to 1.3.24, Kestra-s custom Markdown parser in ui/src/utils/markdown_plugins/link.ts allows a user with permission to create or update a Flow description to inject JavaScript event-handler attributes through the custom [[link]] syntax, causing stored cross-site scripting when another user opens the description or information panel in the Flow list. This issue is fixed in version 1.3.24.
