Since today we have noticed that the new link editor automatically modifies URLs when adding or editing links in emails.
The issue is that the editor decodes already percent-encoded characters inside the URL path, which changes the actual URL and breaks our download links.
Example
Original URL:
https://xxxxxxx.xxx/.platform/customerdata/zbHfKMjdoCqhmXfSccxGpiD7AglaH%2B8DzS7jE%2Bvjbl%2F%2FnDJQggRqcINpVye5ybA3GQrIQtOHPl7GEr%2Bb6kWBgQ%3D%3D
After saving with the link editor:
https://xxxxxxx.xxx/.platform/customerdata/zbHfKMjdoCqhmXfSccxGpiD7AglaH+8DzS7jE+vjbl//nDJQggRqcINpVye5ybA3GQrIQtOHPl7GEr+b6kWBgQ==
The editor converts:
%2B -> +
%2F -> /
%3D -> =
The conversion of %2F into / is particularly problematic because it creates additional path segments, making the URL invalid.
These are signed download URLs, where the exact path is part of the signature. Any modification of the encoded characters invalidates the link.
This worked correctly until today and started after the new link editor was introduced.
Expected behavior
The link editor should preserve the URL exactly as entered. It should not decode or normalize percent-encoded characters within the URL path.
