You might want to add a note when this patch should be removed. Not sure if nixpkgs has a policy about that. |
The "Mailto: Me Your Secrets"[0] paper describes vulnerabilities in multiple email clients regarding the undocumented "attach" field of a mailto URI. This might allow the inclusion of sensitive data in an outgoing email. Pull request NixOS#95758 addresses this issue on a more general level. Claws Mail unfortunately also has problems with mailto URIs[1][2]. Referring to the paper, problems for "attach" and "insert" were found and fixed. These patches, which are not included in a release yet, are hereby added.
