Threats affecting pkg:github/mealie

Mealie versions 3.26.0 through 3.28.0 have a server-side request forgery (SSRF) vulnerability in the OpenID Connect avatar fetch feature. This flaw allows authenticated OIDC users who can control their picture URL to cause the server to send GET requests to arbitrary ports on the identity provider's internal address during login. The vulnerability arises because the allowlist for the identity provider hostname ignores port validation.

Mealie before 3.21.0 fails to validate user ownership in the ratings and favorites endpoints, allowing authenticated attackers to read any user's recipe ratings and favorites by specifying arbitrary user IDs in the URL path. Attackers can access private recipe identifiers, rating values, and favorite flags belonging to other users across different groups or households.
