How to change all links color in CMS?

Hello everyone,

I have a weird issue: I use a CMS for my articles, and when I add a hyperlink, the text is shown in white and is therefore invisible (the background is in white too). The article is here: Queen Clairie - Claire de Belloy - Singer/Songwriter

And here is a screenshot

The color of the text is inherited from “All links”. How can I change it?
