What is CVE-2026-27470?
ZoneMinder, an open-source closed-circuit television software, is affected by a second-order SQL Injection vulnerability. Found in versions 1.36.37 and below, as well as 1.37.61 through 1.38.0, the flaw exists in the getNearEvents() function within web/ajax/status.php. While event field values like Name and Cause are stored using parameterized queries, they are later concatenated into SQL WHERE clauses directly without proper escaping. This allows an authenticated user with privileges to view and edit events to potentially craft and execute arbitrary SQL queries, posing a significant risk to database integrity and security.
Affected Version(s)
zoneminder < 1.36.38 < 1.36.38
zoneminder >= 1.37.61, < 1.38.1 < 1.37.61, 1.38.1
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.
