Executive Summary

YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar filtertags action, which wraps unescaped filterN attribute tokens in quotes and concatenates them into a raw tags.value IN (...) clause.

Analysis

YesWiki before 4.6.7 contains an SQL injection vulnerability in the Bazar filtertags action, which wraps unescaped filterN attribute tokens in quotes and concatenates them into a raw tags.value IN (...) clause. Unauthenticated attackers on default installs can save filtertags markup in a page with a trailing-backslash token that breaks quote parity under MySQL backslash escaping. This lets them inject a five-column UNION subquery to read arbitrary table data such as password hashes. CVSS Score: 8.6. Published: 2026-10-02T12:17:17.653.

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.
