Analysis Summary
# Vulnerability: Drupal Contributed Module Security Updates (June 2026)
## CVE Details
- **CVE ID:** CVE IDs not explicitly listed in the summary advisory (refer to specific SA links for individual mappings).
- **CVSS Score:** N/A (Rated as "Critical" by Drupal Security Team).
- **CWE:** CWE-89 (SQL Injection) and CWE-284 (Improper Access Control).
## Affected Systems
- **Products:**
1. Geolocation Field (Drupal Contributed Module)
2. WissKI (Drupal Contributed Module)
- **Versions:**
1. Geolocation Field: All versions prior to 3.15.0
2. WissKI: All versions prior to 4.2.0
- **Configurations:** Systems running these specific contributed modules within a Drupal CMS environment.
## Vulnerability Description
This advisory covers two distinct critical flaws:
1. **SQL Injection (Geolocation Field):** A flaw exists where user-supplied input is not properly filtered before being used in a database query. An attacker can inject malicious SQL commands to read, modify, or delete sensitive data within the database.
2. **Access Bypass (WissKI):** A flaw in the module's permission logic allows unauthorized users to bypass access controls, potentially gaining access to restricted data or administrative functions they should not have permission to view.
## Exploitation
- **Status:** Not specified (Assume PoC may emerge shortly after advisory release).
- **Complexity:** Low to Medium.
- **Attack Vector:** Network (Remote).
## Impact
- **Confidentiality:** High (Potential for full database exposure and unauthorized data access).
- **Integrity:** High (Potential for unauthorized data modification via SQLi).
- **Availability:** High (Potential for data deletion or service disruption).
## Remediation
### Patches
The Drupal Security Team recommends immediate upgrades to the following versions:
- **Geolocation Field:** Upgrade to version **3.15.0** or later.
- **WissKI:** Upgrade to version **4.2.0** or later.
### Workarounds
- **Geolocation Field:** Disable the module if an immediate update is not possible. Ensure strict WAF (Web Application Firewall) rules are in place to detect common SQL injection patterns.
- **WissKI:** Restrict network access to the application or disable the module until the patch is applied.
## Detection
- **Indicators of Compromise:** Monitor web server logs for suspicious SQL syntax in GET/POST requests (e.g., `UNION SELECT`, `SLEEP()`, or unexpected quotes). Review user access logs for unauthorized access to WissKI-managed entities.
- **Detection methods and tools:** Use Drupal's "Update Manager" to identify outdated modules. Run vulnerability scanners such as `drupal-scan` or specialized DAST tools.
