Snipe-IT before 7.0.10 allows remote code execution (associated with cookie serialization) when an attacker knows the APP_KEY. This is exacerbated by .env files, available from the product's repository, that have default APP_KEY values.
Users with "User:edit" and "Self:api" permissions can promote or demote themselves or other users by performing changes to the group's memberships via API call.This issue affects snipe-it: from v4.6.17 through v6.4.1.
