Authorization Bypass in MoguBlog Exposes Image Category Data

Publication date: 2026-09-11

Last updated on: 2026-09-11

Assigner: VulnCheck

Description
MoguBlog through 6.2 contains an authorization bypass vulnerability in the POST /pictureSort/getPictureSortByUid endpoint, which omits the @AuthorityVerify annotation required to enforce role-based permissions. Authenticated back-office users without image-category permissions can supply a category uid to retrieve restricted image-category records including metadata such as name, cover file uid, sort order and timestamps.

Executive Summary

This is a Broken Function-Level Authorization (BFLA) vulnerability in MoguBlog version 6.2 or earlier. The /pictureSort/getPictureSortByUid endpoint lacks the @AuthorityVerify annotation, which is supposed to enforce role-based permissions. This allows authenticated back-office users without proper image-category permissions to access restricted image-category records by supplying a category UID. The endpoint returns sensitive metadata such as image names, cover file UIDs, sort order, and timestamps.

Detection Guidance

To detect this vulnerability, check if the /pictureSort/getPictureSortByUid endpoint in MoguBlog versions up to 6.2 is accessible without proper authorization. Use a low-privilege admin token to send a POST request to this endpoint with a category UID and verify if it returns sensitive data. Compare this with a protected endpoint like /pictureSort/getList which should deny access.

Impact Analysis

An attacker with low-privilege admin access could exploit this to retrieve sensitive data they are not authorized to view. This includes image metadata and category details, potentially leading to unauthorized access to restricted information or further exploitation of the system.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements for data protection such as GDPR (which mandates strict access controls for personal data) and HIPAA (which requires safeguards for protected health information). Unauthorized data exposure may result in legal penalties and reputational damage.

Mitigation Strategies

Add the @AuthorityVerify annotation to the getPictureSortByUid method in the PictureSortRestApi controller to enforce role-based access control. Audit other methods in the mogu_admin module for similar missing authorization checks and apply the same fix.
