CVE-2025-13082 Overview
CVE-2025-13082 is a User Interface (UI) Misrepresentation of Critical Information vulnerability in Drupal core that enables content spoofing attacks [CWE-451]. The flaw affects multiple release branches, including Drupal core 8.0.0 through 10.4.9, 10.5.0 through 10.5.6, 11.0.0 through 11.1.9, and 11.2.0 through 11.2.8. An unauthenticated attacker can craft input that misrepresents critical information rendered in the Drupal user interface. Successful exploitation requires user interaction, such as clicking a crafted link or viewing manipulated content.
Critical Impact
Attackers can spoof interface content to mislead users, enabling phishing and social-engineering attacks against Drupal-hosted applications.
Affected Products
- Drupal core 8.0.0 before 10.4.9
- Drupal core 10.5.0 before 10.5.6, and 11.0.0 before 11.1.9
- Drupal core 11.2.0 before 11.2.8

Technical Details for CVE-2025-13082
Vulnerability Analysis
The vulnerability is classified under [CWE-451] — User Interface (UI) Misrepresentation of Critical Information. Drupal core renders certain content in a manner that allows an attacker to influence what a legitimate user perceives in the browser. Because the flaw relies on how information is displayed rather than executed, it does not corrupt data or grant direct code execution. Instead, it undermines the integrity of the visual trust boundary between the application and the user.
Exploitation requires network access to the Drupal site and user interaction with attacker-controlled content. The scope remains unchanged, and confidentiality and integrity of stored data are not directly affected. Availability may be marginally impacted through disruption of expected interface behavior. This class of flaw is commonly leveraged in phishing chains, where a spoofed UI element is used to harvest credentials or trick users into performing unintended actions.
Root Cause
The root cause is insufficient validation or encoding of content rendered through the Drupal UI. The vendor advisory categorizes this as content spoofing, indicating that attacker-controlled data influences the presentation layer without appropriate normalization. See the Drupal Security Advisory for vendor-supplied specifics.
Attack Vector
The attack vector is network-based. An attacker delivers a crafted URL or content payload to a Drupal site, then lures a user to interact with it. Because no authentication is required on the attacker's side and no privileges are needed to stage the content, the barrier to exploitation is low. However, the attack succeeds only when a victim engages with the manipulated content.
No verified public exploit or proof-of-concept has been published for CVE-2025-13082. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-13082
Indicators of Compromise
- Unusual inbound requests carrying encoded or specially formatted payloads targeting Drupal rendering endpoints.
- User reports of misleading or unexpected content appearing on Drupal-hosted pages.
- Referrer chains showing off-site links driving traffic to specific Drupal URLs with anomalous query parameters.
Detection Strategies
- Review web server access logs for repeated requests to the same Drupal path with variable parameters designed to influence rendered content.
- Baseline Drupal page output using content integrity monitoring, and alert on rendered content that deviates from expected templates.
- Correlate phishing reports from users with recent Drupal traffic patterns to identify spoofed content campaigns.
Monitoring Recommendations
- Enable verbose logging on the Drupal web tier and forward logs to a centralized analytics platform for retention and search.
- Monitor outbound clicks from Drupal pages that lead to credential-harvesting or attacker-controlled domains.
- Track the version of Drupal core running in production and alert when an out-of-date branch is detected.
How to Mitigate CVE-2025-13082
Immediate Actions Required
- Upgrade Drupal core to 10.4.9, 10.5.6, 11.1.9, or 11.2.8 or later, matching your current release branch.
- Audit custom modules and themes that render user-supplied content, and confirm they inherit the patched behavior from core.
- Notify site editors and administrators of the risk of spoofed content, and remind them to validate URLs before acting on them.
Patch Information
Drupal has released fixed versions in each supported branch. Refer to the Drupal Security Advisory (SA-CORE-2025-007) for the authoritative list of fixed releases and upgrade instructions. Sites running Drupal 8.x or 9.x should migrate to a supported branch, since those releases are no longer maintained.
Workarounds
- Restrict anonymous access to functionality that renders untrusted content until the patch is applied.
- Deploy a web application firewall rule to block requests containing payload patterns associated with content spoofing attempts.
- Apply strict Content Security Policy headers to reduce the impact of spoofed UI elements combined with injected resources.
# Configuration example: upgrade Drupal core via Composer
composer update drupal/core-recommended --with-dependencies
drush updatedb
drush cache:rebuild
