CVE-2025-26908 Overview
CVE-2025-26908 is a SQL Injection vulnerability [CWE-89] in the Gurmehub Kargo Entegratör WordPress plugin (kargo-entegrator). The flaw affects all versions up to and including 1.1.14. Attackers with high privileges can inject malicious SQL statements through unsanitized input passed to backend database queries. Successful exploitation leads to confidentiality compromise and limited availability impact across the WordPress instance. The vulnerability has a scope change, meaning a compromise can affect resources beyond the vulnerable component itself.
Critical Impact
Authenticated attackers can extract sensitive database contents and disrupt WordPress site operations through crafted SQL payloads against the Kargo Entegratör plugin.
Affected Products
- Gurmehub Kargo Entegratör WordPress plugin (kargo-entegrator)
- All versions from initial release through 1.1.14
- WordPress installations with the Kargo Entegratör plugin enabled

Technical Details for CVE-2025-26908
Vulnerability Analysis
The vulnerability stems from improper neutralization of special characters in SQL commands within the Kargo Entegratör plugin. User-supplied input reaches database query construction without proper sanitization or parameterized query usage. Attackers can manipulate query logic by injecting SQL metacharacters such as quotes, semicolons, and UNION operators.
The attack requires network access and high privileges, indicating that the vulnerable functionality resides behind authenticated administrative endpoints. No user interaction is required to trigger exploitation. The scope change indicates that exploitation can affect data and resources beyond the plugin's immediate context, including the broader WordPress database schema.
Root Cause
The root cause is the failure to apply prepared statements or input validation before concatenating user-controlled data into SQL queries [CWE-89]. WordPress provides the $wpdb->prepare() method to safely parameterize queries, but the plugin does not consistently use this API for affected query paths. This pattern allows special elements such as ', --, and ; to alter query semantics.
Attack Vector
An authenticated attacker with elevated WordPress privileges submits crafted parameters to plugin endpoints. The malicious payload modifies SQL query structure, enabling data exfiltration through UNION-based or boolean-based blind injection techniques. Attackers can read sensitive tables including wp_users and wp_options, potentially extracting password hashes and authentication secrets. Refer to the Patchstack SQL Injection Advisory for additional technical context.
Detection Methods for CVE-2025-26908
Indicators of Compromise
- Unexpected SQL syntax tokens such as UNION SELECT, OR 1=1, or SLEEP( appearing in HTTP request parameters to kargo-entegrator plugin endpoints
- WordPress database error messages logged in debug.log referencing malformed queries from the plugin
- Anomalous administrative session activity preceding bulk read operations against wp_users or wp_options tables
Detection Strategies
- Inspect web server access logs for suspicious query strings containing SQL metacharacters targeting plugin URLs
- Enable WordPress query logging and review queries originating from the Kargo Entegratör plugin for unexpected structure
- Deploy web application firewall rules that flag SQL injection signatures against /wp-admin/ paths invoking the plugin
Monitoring Recommendations
- Monitor authenticated administrator and editor activity for unusual request volume to the plugin
- Alert on database errors generated by the plugin during normal operation
- Track changes to sensitive WordPress tables and configuration values that may indicate post-exploitation activity
How to Mitigate CVE-2025-26908
Immediate Actions Required
- Update Kargo Entegratör to a version newer than 1.1.14 once the vendor publishes a patched release
- Audit WordPress administrator and editor accounts and remove unused high-privilege users
- Rotate database credentials and WordPress secret keys if exploitation is suspected
Patch Information
Review the Patchstack SQL Injection Advisory for vendor patch availability. Versions through 1.1.14 are confirmed vulnerable. Site administrators should subscribe to vendor and Patchstack notifications for the patched release.
Workarounds
- Disable and remove the Kargo Entegratör plugin until a patched version is available
- Restrict access to WordPress administrative endpoints using IP allowlisting at the web server or WAF layer
- Enforce least-privilege role assignments to limit the number of accounts capable of reaching the vulnerable code path
