Authenticated arbitrary file write via unsafe ZIP extraction
Published Dec 1, 2025 · Updated Dec 1, 2025
Path traversal in Mogu Blog v2 5.0 through 5.2 allows remote authenticated users to write files outside the extraction directory. FileOperation.unzip joins each untrusted ZIP entry name to the destination path without canonicalizing it or checking that the result remains beneath the destination. Network disk access and an authenticated bearer token are required; writes are limited to locations writable by the application process and can alter configuration or executable content.
