GHSA-p5vf-5754-x7p3: `polymarket-client-sdks` was removed from crates.io for malicious code

Severity: Critical

CVSS Score: 10

It appeared to be typosquatting existing crate [`polymarket-client-sdk`](https://crates.io/crates/polymarket-client-sdk) (`sdks` vs `sdk`) and attempting to steal credentials from local files. The malicious crate had 1 version published on 2026-02-09 and had been downloaded only 33 times. There were no crates depending on this crate on crates.io. Thanks to Roland Peelen for finding and reporting this to the crates.io team!
