CVE-2026-46670: YesWiki: Unauthenticated SQL Injection

Noroxi assessment

Priority: Plan (action score 40/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 80.7% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: yeswiki/yeswiki (Packagist) 4.6.4.

Add it to your regular patch cycle. Upgrade to yeswiki/yeswiki (Packagist) 4.6.4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
