The 475+ malicious pull requests were crafted to look legitimate, targeting repos with permissive contribution settings. The speed and volume suggest automated generation.
The Marimo vulnerability exploitation in under nine hours demonstrates that the window between disclosure and exploitation has collapsed. For founders building on open-source dependencies, these events underscore the need for automated PR review tooling and dependency scanning.
