It is broken in the academic sense that "only" 2^69 operations are required to find a collision on a SHA-1 hashed message as opposed to the 2^80 the designers originally thought.
2^69 is still a huge number so if your secrets are of no interest to a major government/corporation I wouldn't run screaming just yet. You still have the option of other SHA variants (256, 384, 512) or, even better, other algorithms like RIPEMD or (my personal favorite) Whirlpool.
Nevertheless, it's an impressive accomplishment for the Chinese research team
