Executive Summary

Analysis

Phproject before 1.8.7 contains a missing object-level authorization vulnerability in the REST API issue endpoints (single_get, single_comments, single_comments_post) that allows authenticated API key holders to bypass the security.restrict_access confidentiality control by never invoking the allowAccess() authorization routine. Attackers can use a valid API key to read restricted issue contents and comments, including owner and author email addresses, and post unauthorized comments to issues they should not have access to. CVSS Score: 7.1. Published: 2026-10-02T20:17:01.513.

Mooncake through 0.3.13.post1 contains a missing authentication vulnerability in the Store REST service, which binds to 0.0.0.0 without authentication on any route. Unauthenticated attackers can call routes such as /api/get, /api/put, /api/remove_all and /api/mount to read cached KV data with user prompts, inject or delete objects, and mount attacker-described segments.
