CVE-2022-0781
Published: April 11, 2026
Official Description
The Nirweb support WordPress plugin before 2.8.2 does not sanitise and escape a parameter before using it in a SQL statement via an AJAX action (available to unauthenticated users), leading to an SQL injection
Risk Analysis
This SQL Injection vulnerability in the Nirweb support WordPress plugin allows an unauthenticated attacker to inject malicious SQL queries due to improper sanitization and escaping of a parameter. This could lead to unauthorized access to sensitive database information or data manipulation. The confirmed exploitation makes this an urgent concern.
This vulnerability is actively being exploited in the wild and is listed in CISA's KEV catalog. It is remotely exploitable via an AJAX action available to unauthenticated users.
Update the Nirweb support WordPress plugin to version 2.8.2 or newer. Ensure all input, especially parameters used in SQL queries, is properly validated and escaped.
Technical Analysis
CVE-2022-0781 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2022-0781 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
