CVE-2026-55747 The-Pocket CVE debrief

Who should care

Developers and administrators using the pocketflow-coding-agent cookbook example or similar patterns in production applications should review and verify file access controls, implement canonicalization and containment checks for file paths, and monitor for suspicious activity. Security teams and vulnerability management teams should also be aware of the potential risks and take steps to mitigate them.

Technical summary

The pocketflow-coding-agent cookbook example implements a vulnerable _path helper, allowing file access outside the configured working directory. This vulnerability can be exploited by providing absolute paths or traversal sequences in file-tool arguments, potentially leading to unauthorized data reads or writes. The vulnerability has a MEDIUM severity due to its illustrative nature, but applications that copy this pattern into production are affected.

Defensive priority

Review and verify file access controls in cookbook examples and production applications.

Recommended defensive actions

• Review and verify file access controls in cookbook examples and production applications.
• Implement canonicalization and containment checks for file paths.
• Monitor for and restrict absolute paths and traversal sequences in file-tool arguments.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.

Evidence notes

The pocketflow-coding-agent cookbook example implements a vulnerable _path helper. Official records indicate a MEDIUM severity due to its illustrative nature. The vulnerability allows file access outside the configured working directory, potentially leading to unauthorized data reads or writes. Defenders should verify file access controls, monitor for suspicious activity, and implement additional security measures to mitigate potential risks.
