# YesWiki: unauthenticated SQL injection in Bazar search reads password hashes

YesWiki's public Bazar entries search API places field names from the query and searchfields parameters into a backtick-quoted SQL alias that is escaped only with mysqli_real_escape_string. An unauthenticated attacker can inject subqueries to read data such as user password hashes or exhaust database threads with SLEEP().

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed YesWiki version in the wiki's package or version file; versions 4.6.0 up to but not including `4.7.0`, and 5.0.0-alpha1 up to but not including `5.0.0-alpha4`, are affected
- Confirm whether the public Bazar entries search API is reachable from the internet on the instance

## Fix

- Upgrade YesWiki 4.x to `4.7.0` or later
- Upgrade YesWiki 5.0 alpha builds to `5.0.0-alpha4` or later
- Rotate user passwords and session secrets if the instance was reachable before patching, since password hashes may have been read

## From the sources

YesWiki 4.6.0 before 4.7.0 and 5.0.0-alpha1 before 5.0.0-alpha4 contains an unauthenticated SQL injection vulnerability in SearchManager::prepareSearchRequest(). Field names from the query and searchfields parameters of the public Bazar entries search API are placed in a backtick-quoted alias escaped only with mysqli_real_escape_string. Attackers can supply a backtick to inject subqueries, reading data such as user password hashes or exhausting database threads with SLEEP().
