CVE-2026-116211 · Severity: high · CVSS 8.2 · Published 2026-10-25

YesWiki is a collaborative wiki platform that allows users to create and manage content and database entries. A SQL injection flaw in the Bazar entry-creation form allows unauthenticated attackers on default installations to inject malicious SQL and extract sensitive password hashes from the wiki_users table. An attacker can retrieve administrator credentials and gain full control of the wiki and its database.

## How to fix

- Fixed in 4.7.0

## Technical details

The vulnerability exists in PageManager::save() where the attacker-controlled date_maj_fiche parameter is concatenated unescaped into a MySQL INSERT statement, unlike all sibling column values which are properly escaped via mysqli_real_escape_string(). An unauthenticated attacker can break out of the quoted time literal by injecting a double-quote and supply a sub-SELECT to exfiltrate password hashes from wiki_users, or perform blind time-based SQL injection. The default configuration (bazarIgnoreAcls:true, use_captcha:false) allows exploitation via the public Bazar entry form without authentication.
