Recommendation: Monitor — no exploitation signal at the moment.

Kestra is an event-driven orchestration platform. In versions from 1.1.10 and prior, Kestra’s execution-file preview renders user-supplied Markdown (.md) with markdown-it instantiated as html:true and injects the resulting HTML with Vue’s v-html without sanitisation. At time of publication, there are no publicly available patches.
