CVE-2026-39400

MEDIUM

6.1

Description

Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.111, a non-admin user with create_events and run_events privileges can inject arbitrary JavaScript through job output fields (html.content, html.title, table.header, table.rows, table.caption). The server stores this data without sanitization, and the client renders it via innerHTML on the Job Details page. This vulnerability is fixed in 0.9.111.
