MEDIUM 6.5DOWNGRADE

CVE-2024-9000 is a medium-severity flaw (CVSS 6.5) affecting lunary. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In lunary-ai/lunary before version 1.4.26, the checklists.post() endpoint allows users to create or modify checklists without validating whether the user has proper permissions. This missing access control permits unauthorized users to create checklists, bypassing intended permission checks. Additionally, the endpoint does not validate the uniqueness of the slug field when creating a new checklist, allowing an attacker to spoof existing checklist
