In section 1.2 (Definition by convex sets), it is said that a convex curve has no endpoints. How about a line segment on a plane? I would say it is a convex curve (the corresponding convex set being the line segment itself). And it has endpoints.

Also, the link corresponding to the citation [2] directs you to a non-relevant source (Foot and ankle in rheumatoid arthritis). And it does not seem that the actual source (the book by Toponogov) states that convex curves have no endpoints.
