Vulnerabilities

Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting") vulnerability in Drupal Drupal Canvas allows Cross-Site Scripting (XSS). This issue affects Drupal Canvas versions: from 0.0.0 to 1.4.2, from 1.5.0 to 1.5.2, from 1.6.0 to 1.6.1, from 1.7.0 to 1.7.1.

Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Drupal core allows Object Injection. This issue affects Drupal core versions: from 0.0.0 to 10.5.12, from 10.6.0 to 10.6.11, from 11.2.0 to 11.2.14, from 11.3.0 to 11.3.12, from 0.0.0 to 11.0.*, from 0.0.0 to 11.1.*.

CVE-2026-9082 is a critical SQL injection flaw (CWE-89) in Drupal core caused by improper neutralization of special elements used in SQL commands, allowing user-controlled input to alter the queries the application executes. The CVSS vector (AV:N/AC:L/PR:N/UI:N) shows it is remotely exploitable over the network without authentication, special privileges, or user interaction. A successful attacker gains high-impact access to the database (read, modify, or disrupt data), and news reports indicate PostgreSQL-backed sites may additionally be exposed to remote code execution. It affects Drupal core from version 8.9.0 onward across all current major lines, with fixes in 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, and 11.3.10, meaning essentially all unpatched modern Drupal deployments are at risk. The flaw is confirmed under active attack: CISA added it to the KEV catalog on 2026-05-22 and headlines report it is already being exploited in the wild, while EPSS assigns an 87.9% 30-day exploitation probability (100th percentile); no public proof-of-concept is known yet.

Do: Upgrade Drupal core immediately to the patched release for your branch: 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, or 11.3.10, or a later release as applicable, since the flaw is being actively exploited and carries an 87.9% EPSS. Prioritize internet-facing sites and deployments using a PostgreSQL database, which reports say can be pushed to remote code execution, and review web and database logs for signs of exploitation. Under the CISA KEV listing (added 2026-05-22), U.S. federal agencies must apply vendor mitigations per applicable BOD 22-01 guidance or discontinue use of the product if mitigations are unavailable.

Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Drupal core allows Object Injection.This issue affects Drupal core: from 8.0.0 before 10.3.13, from 10.4.0 before 10.4.3, from 11.0.0 before 11.0.12, from 11.1.0 before 11.1.3.

Cross-Site Request Forgery (CSRF) vulnerability in Drupal Gutenberg allows Cross Site Request Forgery.This issue affects Gutenberg: from 0.0.0 before 2.13.0, from 3.0.0 before 3.0.5.

Deserialization of Untrusted Data vulnerability in Drupal Core allows Object Injection.This issue affects Drupal Core: from 7.0 before 7.102, from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9. Drupal core contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so-called gadget chain presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability.

A vulnerability in Drupal Core allows Excessive Allocation.This issue affects Drupal Core: from 10.2.0 before 10.2.2, from 10.1.0 before 10.1.8.

core/authorize.php in Drupal 11.x-dev allows Full Path Disclosure (even when error logging is None) if the value of hash_salt is file_get_contents of a file that does not exist.

Drupal contains a vulnerability with improper handling of structural elements. If this vulnerability is exploited, an attacker may be able to cause a denial-of-service (DoS) condition.

In certain scenarios, Drupal's JSON:API module will output error backtraces. With some configurations, this may cause sensitive information to be cached and made available to anonymous users, leading to privilege escalation. This vulnerability only affects sites with the JSON:API module enabled, and can be mitigated by uninstalling JSON:API. The core REST and contributed GraphQL modules are not affected.

A vulnerability classified as problematic was found in Responsive Menus 7.x-1.x-dev on Drupal. Affected by this vulnerability is the function responsive_menus_admin_form_submit of the file responsive_menus.module of the component Configuration Setting Handler. The manipulation leads to cross site scripting. The attack can be launched remotely. Upgrading to version 7.x-1.7 is able to address this issue. The patch is named 3c554b31d32a367188f44d44857b061eac949fb8. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-227755.

In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system. Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability. This vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9) $config['image.settings']['allow_insecure_derivatives'] or (Drupal 7) $conf['image_allow_insecure_derivatives'] to TRUE. The recommended and default setting is FALSE, and Drupal core does not provide a way to change that in the admin UI. Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing files or image styles after updating.

Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue when the filesystem loader loads templates for which the name is a user input. It is possible to use the `source` or `include` statement to read arbitrary files from outside the templates' directory when using a namespace like `@somewhere/../some.file`. In such a case, validation is bypassed. Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such template names. There are no known workarounds aside from upgrading.
