A critical Metabase SQL injection vulnerability was exploited in zero-day attacks to breach customer instances in data theft attacks, known to impact Framework and Tally.

Metabase disclosed the attacks on Thursday, warning that its Metabase Cloud SaaS platform was compromised through a previously unknown vulnerability affecting versions 1.58 and above. The company warns that self-hosted installations are also vulnerable.

"We recently identified that Metabase Cloud was attacked by someone utilizing an unknown ("0-day") security vulnerability in versions 1.58 and above," Metabase CEO Sameer Al-Sakran warned in a blog post.

Metabase confirmed it blocked the endpoints used for the attack and immediately rolled out a fix for the vulnerability.

"The vulnerability is an unauthenticated SQL injection flaw in Metabase that can ultimately give a remote attacker administrator access to a customer's instance."
