Detailsinfo

A vulnerability was found in MISP up to 2.5.36. It has been rated as critical. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

MISP is an open source threat intelligence and sharing platform. Prior to 2.5.37, a SQL injection vulnerability existed in the handling of user-controlled ordering parameters in the event and shadow attribute listing endpoints. The affected code accepted order or sort values from request parameters and incorporated them into database query ordering clauses without sufficient validation of the requested field name. An attacker with access to the affected endpoints could craft a malicious ordering parameter to manipulate the generated SQL query. Depending on database permissions and query context, this could potentially allow unauthorized access to data, modification of query behavior, or other database-level impact. This vulnerability is fixed in 2.5.37.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-44381 since 05/05/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1505.
