When the Claude Code Action scanned the issue for triage, it followed those instructions, read the process’s environment variables and wrote them back into the repository’s logs. The flaw was demonstrated on a test repo; Anthropic has not issued a public patch or comment yet.\n\n- The problem matters because the action is bundled into dozens of public CI pipelines. Anyone with access to a compromised repo could harvest secrets—API keys, tokens, or passwords—without needing code execution rights.\n\n- Until Anthropic releases a fix, teams should disable the Claude Code Action or audit recent runs for leaked variables.","[\"anthropic\",\"github-actions\",\"security\"]","2026-06-04T16:44:24.000Z","2026-06-04T22:21:58.138Z","2026-06-05T16:22:31.197Z","published",null,[],[25,26,27],"anthropic","github-actions","security",[29],{"name":30,"url":31},"The Next Web","https:\u002F\u002Fthenextweb.com\u002Fnews\u002Fclaude-code-github-action-prompt-injection-flaw",0]
