CVE-2026-49970 plank CVE debrief

Who should care

Users of Laravel-Mediable before version 7.0.0 should be aware of this vulnerability and take steps to mitigate it. Affected operators, platforms, vulnerability-management, and security teams should review and act on this CVE. They should also validate and sanitize user input to prevent path traversal and monitor for suspicious file uploads and directory changes.

Technical summary

The vulnerability is caused by a permissive character-class regex that allows both dot and slash characters combined with an ineffective trailing trim() call. This allows attackers to bypass sanitization and upload files to sensitive locations, enabling remote code execution. The affected product, Laravel-Mediable, has a version prior to 7.0.0 that is vulnerable. Defenders should focus on upgrading to version 7.0.0 or later and validating user input to prevent path traversal.

• Check relevant monitoring, detection, and logs for exposed assets that need extra review
