Fix: plank/laravel-mediable@6d1e7fbCVE-2026-49970 is a Path Traversal vulnerability in plank/laravel-mediable. O3 Security confirms whether CVE-2026-49970 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Laravel-Mediable < 7.0.0 Path Traversal via File::sanitizePath()
Exploitation Status
No confirmed exploitation observed yet
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
plank/laravel-mediableReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for plank/laravel-mediable. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update plank/laravel-mediable to 7.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-49970 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-49970 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-49970. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-49970 in your dependencies?
O3 detects CVE-2026-49970 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
