Description
In Proxmox pmg-api, an argument injection vulnerability exists in the package changelog retrieval functionality. This is caused by improper handling of user-supplied input passed to the underlying apt-get command when fetching package changelogs. It requires authentication but can be exploited in a CSRF-style attack.
