Unauthenticated SQL Injection in YesWiki

Publication date: 2026-08-11

Last updated on: 2026-08-11

Assigner: GitHub, Inc.

Description
YesWiki is a wiki system written in PHP. Prior to version 4.6.4, an unauthenticated SQL injection in the Bazar form-import path (`FormManager::create()`) allows any unauthenticated visitor of a default YesWiki install to inject arbitrary SQL into an `INSERT` statement and read the full database, including `yeswiki_users.password` hashes. Version 4.6.4 fixes the issue.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is an unauthenticated SQL injection vulnerability in YesWiki versions before 4.6.4. It exists in the Bazar form-import path via the FormManager::create() function. An attacker can inject arbitrary SQL into an INSERT statement without authentication, allowing full database access including password hashes.

Detection Guidance

To detect this vulnerability, check if your YesWiki version is below 4.6.4. Inspect the FormManager.php file for unquoted user input concatenation in SQL queries. Monitor network traffic for suspicious POST requests targeting the Bazar form-import path.

Impact Analysis

An attacker could exploit this to dump the entire database, exposing sensitive data like usernames, emails, and password hashes. This could lead to unauthorized account access, data breaches, or further attacks on the system.

Compliance Impact

This vulnerability likely violates compliance requirements for GDPR and HIPAA due to unauthorized data access and potential exposure of personal or sensitive information. It could result in legal penalties, fines, or mandatory breach notifications.

Mitigation Strategies

Immediately upgrade YesWiki to version 4.6.4 or later. If upgrading is not possible, disable the Bazar form-import functionality or restrict access to it. Review database logs for unauthorized access attempts.
