YesWiki: Unauthenticated blind SQL injection in newtextsearch action

CVE-2026-104460High 8.7

← All vulnerabilities

Summary

YesWiki before 4.6.7 contains a blind SQL injection flaw in the {{newtextsearch}} action, which searches Bazar lists. Bazar list option ids are concatenated into SQL queries without escaping. An anonymous attacker who can edit an anonymously editable Bazar list can plant a malicious option id and use search requests as a boolean oracle to read arbitrary database data, including admin password hashes.

Affected

  • YesWiki versions before 4.6.7 (Composer package yeswiki/yeswiki)
  • Exploitation requires a Bazar list that allows anonymous editing and a page using {{newtextsearch}}
  • The first affected version is unknown; sources differ.

Fixed in

  • Upgrade to YesWiki 4.6.7 or later.

Workaround

  • No vendor workaround known.
  • Restrict editing of Bazar lists to authenticated users until the upgrade is done.

Exploitation

  • CISA SSVC: exploitation status PoC, automatable yes, technical impact partial.
  • A public proof-of-concept script is referenced in the advisory and records; no confirmed in-the-wild exploitation found.
  • Not listed in CISA KEV. EPSS 0.00385.

Our recommendation

  • Inventory all YesWiki instances and their versions, including Composer installations.
  • Upgrade to YesWiki 4.6.7 or later.
  • Review Bazar lists that allow anonymous editing and restrict them.
  • Rotate admin passwords after patching, since hashes may have been exposed before the fix.
  • Check web and database logs for unusual search requests on instances exposed before patching.

Public exploits

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)

YesWiki before 4.6.7 contains a blind SQL injection vulnerability in the {{newtextsearch}} action because Bazar list option ids are concatenated into SQL REGEXP/LIKE clauses in actions/newtextsearch.php without escaping. Anonymous attackers can plant a malicious option id in an anonymously editable Bazar list and use search requests as a boolean oracle to read arbitrary database data, including admin password hashes from the yeswiki_users table.
