Detailsinfo

A vulnerability was found in Mealie up to 1.3.x and classified as problematic. Affected by this issue is the function scrape_image. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality. CVE summarizes:

Mealie is a self hosted recipe manager and meal planner. Prior to 1.4.0, the scrape_image function will retrieve an image based on a user-provided URL, however the provided URL is not validated to point to an external location and does not have any enforced rate limiting. The response from the Mealie server will also vary depending on whether or not the target file is an image, is not an image, or does not exist. Additionally, when a file is retrieved the file may remain stored on Mealie’s file system as original.jpg under the UUID of the recipe it was requested for. If the attacker has access to an admin account (e.g. the default [email protected]), this file can then be retrieved. Note that if Mealie is running in a development setting this could be leveraged by an attacker to retrieve any file that the Mealie server had downloaded in this fashion without the need for administrator access. This vulnerability is fixed in 1.4.0.

The advisory is available at securitylab.github.com. This vulnerability is handled as CVE-2024-31993 since 04/08/2024. The exploitation is known to be easy. The attack can only be initiated within the local network. Additional levels of successful authentication are required for exploitation. Technical details are known, but there is no available exploit.

Upgrading to version 1.4.0 eliminates this vulnerability.
