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.

Stored cross-site scripting (XSS) in Cronicle prior to 0.9.111 allows authenticated users with create_events and run_events privileges to inject arbitrary JavaScript through job output fields (html.content, html.title, table.header, table.rows, table.caption). The injected payload is stored server-side without sanitization and executed client-side via innerHTML when other users view the Job Details page, enabling session hijacking, credential theft, or malicious actions performed in the context of the viewing user's session. …
