CVE-2026-8492 Overview
CVE-2026-8492 is a Modification of Assumed-Immutable Data (MAID) vulnerability in the Drupal Translate Drupal with GTranslate contributed module. The flaw enables Resource Location Spoofing, allowing an authenticated attacker with high privileges to alter data the application assumes cannot be modified. The issue affects all versions of the module from 0.0.0 before 3.0.5. The vulnerability is classified under CWE-471, and Drupal has published a security advisory addressing the module.
Critical Impact
An authenticated attacker with elevated privileges can spoof resource locations within the module, undermining the integrity of translation-related data served to site visitors.
Affected Products
- Drupal contributed module: Translate Drupal with GTranslate
- Versions from 0.0.0 before 3.0.5
- Drupal sites with the GTranslate module installed and enabled

Technical Details for CVE-2026-8492
Vulnerability Analysis
The vulnerability stems from the module treating certain data as immutable when it is actually attacker-controllable. Under [CWE-471] (Modification of Assumed-Immutable Data), the application trusts values that can be modified by a privileged user, leading to integrity issues. In this case, the spoofable input influences the resource location used by the translation workflow.
Exploitation requires network access and high privileges on the target Drupal site. No user interaction is needed. The impact is limited to integrity, with no direct effect on confidentiality or availability. The EPSS probability is 0.018%, reflecting a very low predicted exploitation likelihood in the near term.
Root Cause
The Translate Drupal with GTranslate module accepts input that determines the location of a resource without enforcing immutability or strict validation. Because the module assumes the value is fixed, the downstream logic acts on the modified value without rechecking its authenticity. This trust boundary failure enables Resource Location Spoofing.
Attack Vector
The attack vector is network-based. An authenticated user with high privileges submits crafted input through the module's interface or APIs to alter the assumed-immutable resource location. The spoofed location is then used by the module, causing the application to operate on attacker-influenced data. No verified public exploit or proof-of-concept is available at this time.
No verified exploit code is publicly available. Refer to the Drupal Security Advisory for vendor-supplied technical details.
Detection Methods for CVE-2026-8492
Indicators of Compromise
- Unexpected changes to GTranslate module configuration entries in the Drupal configuration store
- Outbound requests from the Drupal server to unfamiliar translation or resource endpoints
- Module-related audit log entries showing configuration writes by non-administrative or rarely active privileged accounts
Detection Strategies
- Inventory all Drupal sites and identify those running Translate Drupal with GTranslate below version 3.0.5
- Review Drupal watchdog logs and configuration change history for modifications to GTranslate settings
- Correlate privileged user sessions with configuration changes to the module to identify abuse of high-privilege accounts
Monitoring Recommendations
- Enable Drupal database logging and forward watchdog events to a centralized log platform
- Alert on configuration changes affecting contributed modules, especially translation and localization components
- Monitor outbound HTTP traffic from web servers for connections to unexpected translation service hosts
How to Mitigate CVE-2026-8492
Immediate Actions Required
- Upgrade Translate Drupal with GTranslate to version 3.0.5 or later on all affected Drupal sites
- Audit accounts with high privileges and remove unused or unnecessary administrative roles
- Review recent configuration changes to the GTranslate module and revert any unauthorized modifications
Patch Information
Drupal has released version 3.0.5 of the Translate Drupal with GTranslate module to remediate this issue. Site administrators should follow the guidance in the Drupal Security Advisory and update through the standard Drupal module update workflow.
Workarounds
- If immediate patching is not possible, disable the Translate Drupal with GTranslate module until the upgrade can be applied
- Restrict access to module configuration pages to a minimal set of trusted administrators
- Enforce multi-factor authentication for all Drupal accounts holding high-privilege roles
# Update the GTranslate module using Drush
drush pm:update gtranslate
drush updatedb
drush cache:rebuild
# Verify installed version is 3.0.5 or later
drush pm:list --type=module --status=enabled | grep -i gtranslate
