Path Traversal in plank/laravel-mediable (CVE-2026-49970)

Summary

Path traversal in plank/laravel-mediable (CVE-2026-49970). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 7.0.0 or later.

Original description

The description as published by the source.

Laravel-Mediable before 7.0.0 contains a path traversal vulnerability in the File::sanitizePath() function that allows attackers to write uploaded files to arbitrary locations by controlling the directory argument passed to MediaUploader::toDestination(). Attackers can exploit the permissive character-class regex that allows both dot and slash characters combined with an ineffective trailing trim() call to bypass sanitization and upload files to sensitive locations such as the document root, environment configuration files, or application configuration directories, enabling remote code execution.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'plank/laravel-mediable' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で plank/laravel-mediable を grep し、稼働しているサービス・バージョンを把握する。
