SHA-1 is thought to become vulnerable to collision attacks
SHA-1 is actually known to be, not just thought to become, vulnerable to collision attacks at less than the full bit strength of the hash[0].
The important part is the pre-image resistance, of which there is no known attack.

- baby 11y agoRight, it's more than certain now that with time we will be able to find a collision ("an estimated cost of $2.77M to break a single hash value by renting CPU power from cloud servers"). But there is a difference between the theory and actually finding a collision. And then a huge difference as well on how to exploit that.
