What happened

Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.124, an authenticated non-admin with run_events, create_events, or edit_events privilege can supply undeclared keys in event params through api_create_event, api_update_event, or api_run_event. lib/api.js and lib/api/event.js validate the parameter object without restricting its keys, and lib/job.

js uppercases those keys and applies them to the child process environment after administrator-defined plugin variables. A key that collides with a security-sensitive environment variable can therefore override the plugin execution context and may cause privilege escalation, arbitrary code execution, data access, or service disruption depending on the plugin and runtime. This issue is fixed in version 0.9.124.

About this data

This record was ingested from a data source. Retrieved: Nov 5, 2026, 22:25 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
