Cosmos Labs is urging operators of public blockchains to immediately halt and upgrade their Cosmos EVM module if they are running versions below v0.6.2 or v0.7.2. The recommendation, posted Tuesday at 11:19 a.m. New York time, comes after a shared bug drained three networks.
The specific versions at risk
The advisory applies to any public chain using the Cosmos EVM module. Versions below the two patched releases — v0.6.2 and v0.7.2 — are the ones in the crosshairs. Cosmos Labs didn't mince words: halt and upgrade. This isn't a routine update notice; it's a stop-everything kind of alert.
What triggered the alarm
The bug isn't theoretical. Three networks have already been drained because of it. That's the kind of track record that gets an immediate advisory posted on a Tuesday morning. The shared nature of the vulnerability is the core issue — it's not an isolated incident affecting one chain, but a flaw that hits any chain running the vulnerable code.
Inside the patch
The patched releases, v0.6.2 and v0.7.2, are the fixes. Chains that are already on a version above those numbers don't need to do anything. For everyone else, the path is clear: halt, upgrade, resume. The halt isn't optional if the goal is to avoid the same drain that hit those three networks.
What operators should do now
If you're running a public chain with the Cosmos EVM module, the next step is to check your version number. If it's below v0.6.2 or v0.7.2, stop the chain and upgrade. The fact that this got a time-stamped advisory on a Tuesday morning suggests there's a real sense of urgency behind the scenes.
