## What is CVE-2026-49970?

CVE-2026-49970 is a high-severity path traversal vulnerability in plank laravel-mediable, published on 13 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
