Drupal core - Critical - Cache poisoning - SA-CORE-2023-006

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.

CWE-200Sep 28, 2023
CVSS7.5v3.1EPSS0.694%PoCs0SignalsSTIX

Lack of domain validation in Druple core

The Media oEmbed iframe route does not properly validate the iframe domain setting, which allows embeds to be displayed in the context of the primary domain. Under certain circumstances, this could lead to cross-site scripting, leaked cookies, or other vulnerabilities.

CWE-79Apr 26, 2023
CVSS6.1v3.1EPSS0.526%PoCs0SignalsSTIX

Drupal core arbitrary PHP code execution

Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010). However, the protections for these two vulnerabilities previously did not work correctly together. As a result, if the site were configured to allow the upload of files with an htaccess extension, these files' filenames would not be properly sanitized. This could allow…

CVSS7.2v3.1EPSS1.42%PoCs0SignalsSTIX

Drupal core - Moderately critical - Access bypass - SA-CORE-2023-005

The file download facility doesn't sufficiently sanitize file paths in certain situations. This may result in users gaining access to private files that they should not have access to. Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing private files after updating.

CWE-863Apr 26, 2023
CVSS6.5v3.1EPSS0.54%PoCs0SignalsSTIX

Improper input validation in Drupal core

Drupal core's form API has a vulnerability where certain contributed or custom modules' forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data.

CWE-20Apr 26, 2023
CVSS7.5v3.1EPSS0.568%PoCs0SignalsSTIX

Drupal core Information Disclosure vulnerability

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)…

CVSS7.5v3.1EPSS0.667%PoCs0SignalsSTIX

Access bypass in Drupal Core

Under certain circumstances, the Drupal core form API evaluates form element access incorrectly. This may lead to a user being able to alter data they should not have access to. No forms provided by Drupal core are known to be vulnerable. However, forms added through contributed or custom modules or themes may be affected.

CVSS6.5v3.1EPSS0.59%PoCs0SignalsSTIX

Access bypass in Drupal core

Drupal 9.3 implemented a generic entity access API for entity revisions. However, this API was not completely integrated with existing permissions, resulting in some possible access bypass for users who have access to use revisions of content generally, but who do not have access to individual items of node and media content. This vulnerability only affects sites using Drupal's revision system.

CWE-863Apr 26, 2023
CVSS5.4v3.1EPSS0.423%PoCs0SignalsSTIX

Incorrect authorization in Drupal core

The Quick Edit module does not properly check entity access in some circumstances. This could result in users with the "access in-place editing" permission viewing some content they are are not authorized to access. Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed.

CVSS6.5v3.1EPSS0.769%PoCs0SignalsSTIX

Improper input validation in Drupal core

Drupal core's form API has a vulnerability where certain contributed or custom modules' forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data.

CWE-20Feb 16, 2022
CVSS7.5v3.1EPSS1.28%PoCs0SignalsSTIX

Drupal core access bypass vulnerability

Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled are not affected.

CVSS7.5v3.1EPSS1.05%PoCs0SignalsSTIX

Incorrect Authorization in Drupal core

The QuickEdit module does not properly check access to fields in some circumstances, which can lead to unintended disclosure of field data. Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed.

CVSS6.5v3.1EPSS0.805%PoCs0SignalsSTIX

Exposure of Resource to Wrong Sphere in Drupal Core

Information Disclosure vulnerability in file module of Drupal Core allows an attacker to gain access to the file metadata of a permanent private file that they do not have access to by guessing the ID of the file. This issue affects: Drupal Core 8.8.x versions prior to 8.8.10; 8.9.x versions prior to 8.9.6; 9.0.x versions prior to 9.0.6.

CWE-668Feb 11, 2022
CVSS7.5v3.1EPSS1.11%PoCs0SignalsSTIX

Cross-Site Request Forgery in Drupal core

The QuickEdit module does not properly validate access to routes, which could allow cross-site request forgery under some circumstances and lead to possible data integrity issues. Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. Removing the "access in-place editing" permission from untrusted users will not fully mitigate the vulnerability.

CWE-352Feb 11, 2022
CVSS6.5v3.1EPSS0.456%PoCs0SignalsSTIX

Unrestricted Upload of File with Dangerous Type in Drupal core

Drupal's JSON:API and REST/File modules allow file uploads through their HTTP APIs. The modules do not correctly run all file validation, which causes an access bypass vulnerability. An attacker might be able to upload files that bypass the file validation process implemented by modules on the site.

Drupal core Cross-site Scripting (XSS) vulnerability

Cross-site Scripting (XSS) vulnerability in Drupal core's sanitization API fails to properly filter cross-site scripting under certain circumstances. This issue affects: Drupal Core 9.1.x versions prior to 9.1.7; 9.0.x versions prior to 9.0.12; 8.9.x versions prior to 8.9.14; 7.x versions prior to 7.80.

CWE-79Feb 11, 2022
CVSS6.1v3.1EPSS0.643%PoCs0SignalsSTIX

Access bypass in Drupal Core 8/9

Access Bypass vulnerability in Drupal Core allows for an attacker to leverage the way that HTML is rendered for affected forms in order to exploit the vulnerability. This issue affects: Drupal Core 8.8.x versions prior to 8.8.10; 8.9.x versions prior to 8.9.6; 9.0.x versions prior to 9.0.6.

Drupal core - Highly critical - Remote Code Execution

Some field types do not properly sanitize data from non-form sources in Drupal 8.5.x before 8.5.11 and Drupal 8.6.x before 8.6.10. This can lead to arbitrary PHP code execution in some cases. A site is only affected by this if one of the following conditions is met: The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows PATCH or POST requests, or the site has another web services module enabled, like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupa…

Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-004

A remote code execution vulnerability exists within multiple subsystems of Drupal 7.x and 8.x. This potentially allows attackers to exploit multiple attack vectors on a Drupal site, which could result in the site being compromised. This vulnerability is related to Drupal core - Highly critical - Remote Code Execution - SA-CORE-2018-002. Both SA-CORE-2018-002 and this vulnerability are being exploited in the wild.
