Description

Manticore Search versions 27.0.0 before 28.4.4 fail to validate permissions for all statements in multi-statement SQL requests, allowing read-only users to execute unauthorized queries. Attackers can append additional SELECT statements after the first statement to read credential tables and obtain password hashes that authenticate as administrators without plaintext recovery.
