CVE-2026-40836
Full vulnerability record from the local CVENow database.
Description
An low privileged remote attacker can exploit an unauthenticated SQL Injection vulnerability in the inmessage model due to improper neutralization of special elements in a SQL DELETE command allowing for reading the whole database and deleting entries in a non critical table. This can result in a total loss of confidentiality and some loss of integrity.
