EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.7%, top 25% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
