Koko Analytics is an open-source analytics plugin for WordPress. Versions prior to 2.1.3 are vulnerable to arbitrary SQL execution through unescaped analytics export/import and permissive admin SQL import. Unauthenticated visitors can submit arbitrary path (`pa`) and referrer (`r`) values to the public tracking endpoint in src/Resources/functions/collect.php, which stores those strings verbatim in the analytics tables. The admin export logic in src/Admin/Data_Export.php writes these stored values directly into SQL INSERT statements without escaping. A crafted path such as "),('999','x');DROP TABLE wp_users;-- breaks out of the value list.
When an administrator later imports that export file, the import handler in src/Admin/Data_Import.php reads the uploaded SQL with file_get_contents, performs only a superficial header check, splits on semicolons, and executes each statement via $wpdb->query with no validation of table names or statement types. Additionally, any authenticated user with manage_koko_analytics can upload an arbitrary .sql file and have it executed in the same permissive way.
Combined, attacker-controlled input flows from the tracking endpoint into exported SQL and through the import execution sink, or directly via malicious uploads, enabling arbitrary SQL execution. In a worst-case scenario, attackers can achieve arbitrary SQL execution on the WordPress database, allowing deletion of core tables (e.g., wp_users), insertion of backdoor administrator accounts, or other destructive/privilege-escalating actions. Version 2.1.3 patches the issue.
The vulnerability has been scored with a CVSS score of 8.3, categorizing it as high severity. This score reflects a high attack vector via the network, high attack complexity, and the requirement for user interaction, indicating the potential for significant impact on confidentiality, integrity, and availability.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
CWE-89: SQL Injection is the identified weakness in this case. The affected component is the Koko Analytics plugin, and the versions prior to 2.1.3 are vulnerable.
The vulnerability was published on January 19, 2026, and the last modification to the CVE record was made on March 9, 2026.
Technical Analysis
The root cause of this vulnerability stems from the lack of input validation and sanitization in the SQL export and import functionalities of the Koko Analytics plugin. Attackers can leverage this flaw by submitting crafted inputs that break out of the expected value context, allowing them to execute arbitrary SQL commands.
The attack vector is network-based, requiring an attacker to send crafted data to the public tracking endpoint. The complexity of the attack is deemed high, as it necessitates user interaction, such as an administrator importing malicious SQL data.
There are no privileges required for the attack, but user interaction is necessary for the import phase. The confidentiality, integrity, and availability impacts are all rated high, as an attacker could manipulate the database fully.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, potential deletion of critical database tables, and the insertion of backdoor accounts, leading to further exploitation. The blast radius of this vulnerability extends to any WordPress site utilizing the Koko Analytics plugin, affecting a wide range of installations.
Organizations should address in priority patch cycle, given the potential for immediate and severe impacts on their operations. The combination of high CVSS score and the permissive nature of the vulnerability necessitates swift action.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch, specifically versions prior to 2.1.3 are affected by this vulnerability.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to version 2.1.3 or later of the Koko Analytics plugin. If immediate patching is not possible, consider implementing workarounds such as disabling the analytics export/import functionality and monitoring user actions closely.
Additionally, organizations can enhance security by applying configuration hardening measures, implementing network controls, and regularly monitoring for any unusual database activities.
For effective validation of remediation effectiveness, organizations should engage in penetration testing that exercises the patched code path.
Detection Guidance
Organizations should monitor logs for any suspicious SQL queries, especially those that attempt to drop tables or insert unauthorized users. Additionally, behavioral anomalies that deviate from normal admin operations should be flagged for further investigation.
Network signatures indicating unusual spikes in database queries may also serve as indicators of this vulnerability being exploited.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2026-22850 lies in its illustration of the risks associated with poorly validated user input in web applications. This vulnerability highlights a pattern where attackers can exploit weaknesses in input handling to execute arbitrary SQL commands, posing severe risks to data integrity and confidentiality.
Security teams should take away critical lessons regarding the importance of implementing stringent input validation and sanitization practices. Regular code reviews and security assessments can help identify such vulnerabilities before they are exploited.
