What is CVE-2026-61461?

Dify, prior to version 1.16.0-rc1, is susceptible to a SQL injection vulnerability within its MyScale vector store backend. This issue arises from the failure to properly sanitize search parameters in the search_by_full_text method, allowing attackers to execute arbitrary SQL commands. By injecting malicious SQL through unsanitized input, adversaries can manipulate the data stored in the underlying ClickHouse database, which could lead to unauthorized data access, modification, or deletion.

Affected Version(s)

dify 0 < 1.16.0-rc1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
