Critical CVSS 9.8
CVE-2026-46670
NVD analysis in progress
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.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Unescaped input is placed into an SQL query, letting the attacker read or alter the database (SQL injection).
- Likelihood
- Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
