Summary

Mealie versions 3.26.0 through 3.28.0 contain a server-side request forgery flaw (CWE-918) in the OpenID Connect avatar fetch. The fetch ignores ports when it checks the identity provider hostname against an allowlist. An authenticated OIDC user who controls their picture URL can make the server send GET requests to arbitrary ports on the provider's internal address on each login.
