CVE-2026-13242: Drupal Geolocation Field SQLi Vulnerability

CVE-2026-13242 Overview

CVE-2026-13242 is a SQL Injection vulnerability in the Drupal Geolocation Field contributed module. The flaw stems from improper neutralization of special elements passed into SQL commands [CWE-89]. Attackers can send crafted requests over the network without authentication or user interaction to influence backend database queries. The issue affects all Geolocation Field versions from 0.0.0 up to and including 3.15.0. According to the Drupal Security Advisory, site operators using the module should upgrade to a fixed release.

Critical Impact
Unauthenticated attackers can inject SQL through the Geolocation Field module, potentially exposing or altering data stored in Drupal databases.

Affected Products

Drupal Geolocation Field module versions 0.0.0 through 3.15.0
Drupal sites with the Geolocation Field contributed module installed and enabled
Any Drupal deployment exposing views or endpoints that consume Geolocation Field input

Technical Details for CVE-2026-13242

Vulnerability Analysis

The Geolocation Field module extends Drupal with latitude and longitude data types, views filters, and proximity-based query features. The vulnerability arises when user-supplied input reaches SQL queries without proper parameterization or sanitization. Because the attack vector is network-based and requires no authentication or user interaction, any exposed page or endpoint consuming Geolocation Field input becomes an entry point. The confidentiality and integrity impact is limited in scope, consistent with partial data exposure or modification rather than full database compromise.

Root Cause

The root cause is Improper Neutralization of Special Elements used in an SQL Command [CWE-89]. Query construction inside the module concatenates or interpolates values that originate from HTTP parameters into SQL statements. Drupal's database abstraction layer supports placeholder binding, but the affected code paths do not consistently use it. Attackers who supply SQL metacharacters can alter the resulting query structure.

Attack Vector

A remote attacker sends crafted HTTP requests containing SQL metacharacters to a Drupal page or view backed by the Geolocation Field module. The malicious payload is embedded in a parameter that the module forwards into a database query. When the query executes, the injected fragment runs against the Drupal database backend, enabling limited data disclosure or modification. No credentials or user interaction are required.

No public proof-of-concept code is available. Refer to the Drupal Security Advisory for vendor-provided technical context.

Detection Methods for CVE-2026-13242

Indicators of Compromise

HTTP requests to Geolocation Field-backed views or routes containing SQL metacharacters such as single quotes, UNION, SELECT, or comment sequences (--, #)
Unexpected database errors in Drupal watchdog or dblog entries referencing geolocation query paths
Anomalous outbound query patterns from the Drupal web server to the database tier

Detection Strategies

Inspect Drupal request logs for parameter values targeting Geolocation Field endpoints that include SQL syntax
Enable database query logging in non-production environments to identify unparameterized queries originating from the module
Deploy Web Application Firewall (WAF) rules that flag SQL Injection patterns against Drupal view and REST paths

Monitoring Recommendations

Alert on spikes in HTTP 500 responses or PDOException entries associated with geolocation views
Track authentication and privilege changes on the Drupal database user to detect follow-on activity
Correlate WAF SQL Injection detections with the specific URLs exposed by the Geolocation Field module

How to Mitigate CVE-2026-13242

Immediate Actions Required

Identify all Drupal sites running Geolocation Field version 3.15.0 or earlier using drush pm:list or the Extend admin page
Upgrade the Geolocation Field module to a fixed release per the Drupal Security Advisory
Restrict access to Geolocation Field-backed views and endpoints until the module is patched
Review database logs for evidence of prior injection attempts against affected routes

Patch Information

Drupal has published guidance in advisory SA-CONTRIB-2026-062. Administrators should update the Geolocation Field module to a version later than 3.15.0 and clear the Drupal cache after deployment. Consult the Drupal Security Advisory for exact fixed-version identifiers and release notes.

Workarounds

Temporarily disable the Geolocation Field module on affected sites until upgrade is possible
Apply WAF rules that block SQL Injection payloads targeting Drupal view and REST endpoints exposing geolocation parameters
Enforce least-privilege on the Drupal database user to limit the impact of any successful injection

bash

# Configuration example
drush pm:list --type=module --status=enabled | grep geolocation
drush pm:update geolocation_field
drush cache:rebuild
