## Technical details

The accountsController.uploadImage endpoint fails to properly validate the _id and username parameters, allowing authenticated users to supply path traversal sequences such as /../../../x to bypass the incomplete sanitization from CVE-2022-1752. An attacker can craft a request with a malicious username to write PNG, JPG, JPEG, or GIF files outside the intended public/uploads/users directory, potentially overwriting system files or other users' avatars with controlled content.
