Flaw in Claude Code GitHub Action Exposes Repositories to Hijacking
A security researcher discovered a logic hole in Anthropic's Claude Code GitHub Action that could let attackers hijack vulnerable public repositories with just a single opened GitHub issue. This flaw exploited broad read and write permissions, putting countless repositories at risk.
