The vulnerability CVE-2025-13813 affects moxi159753 Mogu Blog v2 versions up to 5.2. It involves the Storage Management component, specifically the /storage/ endpoint. This endpoint handles file storage operations within the blog application. The issue stems from missing authorization checks, allowing unauthorized access. Attackers can remotely exploit this without authentication. The manipulation leads to unauthorized actions like viewing or modifying stored files. Attack complexity is high, requiring advanced knowledge. Exploitability is difficult due to this complexity. However, public exploit availability increases risk. The vendor was contacted but did not respond. No patch has been released yet. CVSS 4.0 score is 6.3 MEDIUM. The vector string is CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P. This indicates network attack vector, high attack complexity, and low impacts on confidentiality, integrity, and availability. The vulnerability could lead to data leakage or tampering. Organizations using Mogu Blog should immediately secure the /storage/ endpoint. Workarounds like web application firewalls are recommended. Monitoring for unauthorized access is crucial until a fix is available.
