On June 6th, Cosmos Hub said on the X platform at 4:32 am today that Cosmos Hub is experiencing a temporary chain outage. Later, it said in a follow-up post that during the v17 upgrade, Hub validators patched security bugs in the Liquid Staking module (LSM). After most validators implemented the patch to fix the vulnerability, Cosmos Hub said a few minutes ago that the previous issue has been fixed and Cosmos Hub is generating blocks again. Informal Systems and Hypha Cosmos will release a post-mortem analysis with all the details as soon as possible.
