The BOTCHA Spam Prevention module 7.x-1.x before 7.x-1.6, 7.x-2.x before 7.x-2.1, and 7.x-3.x before 7.x-3.3 for Drupal, when the debugging level is set to 5 or 6, logs the content of submitted forms, which allows context-dependent users to obtain sensitive information such as usernames and passwords by reading the log file.

Drupal 5.x before 5.19 and 6.x before 6.13 does not properly sanitize failed login attempts for pages that contain a sortable table, which includes the username and password in links that can be read from (1) the HTTP referer header of external web sites that are visited from those links or (2) when page caching is enabled, the Drupal page cache.

Unspecified vulnerability in Drupal 5.x before 5.17 and 6.x before 6.11, as used in vbDrupal before 5.17.0, allows user-assisted remote attackers to obtain sensitive information by tricking victims into visiting the front page of the site with a crafted URL and causing form data to be sent to an attacker-controlled site, possibly related to multiple / (slash) characters that are not properly handled by includes/bootstrap.inc, as demonstrated using the search box. NOTE: this vulnerability can be leveraged to conduct cross-site request forgery (CSRF) attacks.

Unspecified vulnerability in Internationalization (i18n) Translation 5.x before 5.x-2.5, a module for Drupal, allows remote attackers with "translate node" permissions to bypass intended access restrictions and read unpublished nodes via unspecified vectors.

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.

Access bypass vulnerability in of Drupal Core Workspaces allows an attacker to access data without correct permissions. The Workspaces module doesn't sufficiently check access permissions when switching workspaces, leading to an access bypass vulnerability. An attacker might be able to see content before the site owner intends people to see the content. This vulnerability is mitigated by the fact that sites are only vulnerable if they have installed the experimental Workspaces module. This issue affects Drupal Core8.8.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.

The Image module in Drupal 7.x before 7.19, when a private file system is used, does not properly restrict access to derivative images, which allows remote attackers to read derivative images of otherwise restricted images via unspecified vectors.

Unspecified vulnerability in the PayPal Website Payments Standard functionality in the Ubercart module 5.x before 5.x-1.9 and 6.x before 6.x-2.1 for Drupal, when a custom checkout completion message is enabled, allows attackers to obtain sensitive information via unknown vectors.

The node selection interface in the WYSIWYG editor (CKEditor) in the Node Embed module 6.x-1.x before 6.x-1.5 and 7.x-1.x before 7.x-1.0 for Drupal does not properly check permissions, which allows remote attackers to bypass intended access restrictions and read node titles.

Unspecified vulnerability in Userpoints 6.x before 6.x-1.1, a module for Drupal, allows remote authenticated users with "View own userpoints" permissions to read the userpoint data of arbitrary users via unknown attack vectors.

The Webform module 5.x before 5.x-2.8 and 6.x before 6.x-2.8, a module for Drupal, does not prevent caching of a page that contains token placeholders for a default value, which allows remote attackers to read session variables via unspecified vectors.

The Views module 7.x-3.x before 7.x-3.14 in Drupal 7.x and the Views module in Drupal 8.x before 8.1.3 might allow remote authenticated users to bypass intended access restrictions and obtain sensitive Statistics information via unspecified vectors.

The "have you forgotten your password" links in the User module in Drupal 7.x before 7.43 and 8.x before 8.0.4 allow remote attackers to obtain sensitive username information by leveraging a configuration that permits using an email address to login and a module that permits logging in.

The recycle bin feature in the Monster Menus module 7.x-1.21 before 7.x-1.24 for Drupal does not properly remove nodes from view, which allows remote attackers to obtain sensitive information via an unspecified URL pattern.

Guzzle is an open source PHP HTTP client. In affected versions `Authorization` headers on requests are sensitive information. On making a request using the `https` scheme to a server which responds with a redirect to a URI with the `http` scheme, we should not forward the `Authorization` header on. This is much the same as to how we don't forward on the header if the host changes. Prior to this fix, `https` to `http` downgrades did not result in the `Authorization` header being removed, only changes to the host. Affected Guzzle 7 users should upgrade to Guzzle 7.4.4 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an alternative approach which would be to use their own redirect middleware. Alternately users may simply disable redirects all together if redirects are not expected or required.

The Entity Registration module 7.x-1.x before 7.x-1.5 for Drupal allows remote attackers to obtain sensitive event registration information by leveraging the "Register other accounts" permission and knowledge of usernames.

Guzzle is an open source PHP HTTP client. In affected versions the `Cookie` headers on requests are sensitive information. On making a request using the `https` scheme to a server which responds with a redirect to a URI with the `http` scheme, or on making a request to a server which responds with a redirect to a a URI to a different host, we should not forward the `Cookie` header on. Prior to this fix, only cookies that were managed by our cookie middleware would be safely removed, and any `Cookie` header manually added to the initial request would not be stripped. We now always strip it, and allow the cookie middleware to re-add any cookies that it deems should be there. Affected Guzzle 7 users should upgrade to Guzzle 7.4.4 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an alternative approach to use your own redirect middleware, rather than ours. If you do not require or expect redirects to be followed, one should simply disable redirects all together.

Drupal 6.x before 6.37 and 7.x before 7.39 allows remote attackers to obtain sensitive node titles by reading the menu.

The Render cache system in Drupal 7.x before 7.38, when used to cache content by user role, allows remote authenticated users to obtain private content viewed by user 1 by reading the cache.

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.

Guzzle is a PHP HTTP client. Guzzle prior to versions 6.5.6 and 7.4.3 contains a vulnerability with the cookie middleware. The vulnerability is that it is not checked if the cookie domain equals the domain of the server which sets the cookie via the Set-Cookie header, allowing a malicious server to set cookies for unrelated domains. The cookie middleware is disabled by default, so most library consumers will not be affected by this issue. Only those who manually add the cookie middleware to the handler stack or construct the client with ['cookies' => true] are affected. Moreover, those who do not use the same Guzzle client to call multiple domains and have disabled redirect forwarding are not affected by this vulnerability. Guzzle versions 6.5.6 and 7.4.3 contain a patch for this issue. As a workaround, turn off the cookie middleware.

The Janrain Engage (formerly RPX) module for Drupal 6.x-1.x. 6.x-2.x before 6.x-2.2, and 7.x-2.x before 7.x-2.2 stores user profile data from Engage in session tables, which might allow remote attackers to obtain sensitive information by leveraging a separate vulnerability.

The Ubercart AJAX Cart 6.x-2.x before 6.x-2.1 for Drupal stores the PHP session id in the JavaScript settings array in page loads, which might allow remote attackers to obtain sensitive information by sniffing or reading the cache of the HTML of a webpage.

The CDN module 6.x-2.2 and 7.x-2.2 for Drupal, when running in Origin Pull mode with the "Far Future expiration" option enabled, allows remote attackers to read arbitrary PHP files via unspecified vectors, as demonstrated by reading settings.php.

Drupal 6.x before 6.23 and 7.x before 7.11 does not verify that Attribute Exchange (AX) information is signed, which allows remote attackers to modify potentially sensitive AX information without detection via a man-in-the-middle (MITM) attack.

Drupal 7.0 allows remote attackers to obtain sensitive information via a direct request to a .php file, which reveals the installation path in an error message, as demonstrated by modules/simpletest/tests/upgrade/drupal-6.upload.database.php and certain other files.

In Drupal versions 8.4.x versions before 8.4.5 users with permission to post comments are able to view content and comments they do not have access to, and are also able to add comments to this content. This vulnerability is mitigated by the fact that the comment system must be enabled and the attacker must have permission to post comments.

The taxonomy module in Drupal 7.x before 7.52 and 8.x before 8.2.3 might allow remote authenticated users to obtain sensitive information about taxonomy terms by leveraging inconsistent naming of access query tags.

Apache HttpClient 4.x before 4.1.1 in Apache HttpComponents, when used with an authenticating proxy server, sends the Proxy-Authorization header to the origin server, which allows remote web servers to obtain sensitive information by logging this header.

The XML Editor in Microsoft InfoPath 2007 SP2 and 2010; SQL Server 2005 SP3 and SP4 and 2008 SP1, SP2, and R2; SQL Server Management Studio Express (SSMSE) 2005; and Visual Studio 2005 SP1, 2008 SP1, and 2010 does not properly handle external entities, which allows remote attackers to read arbitrary files via a crafted .disco (Web Service Discovery) file, aka "XML External Entities Resolution Vulnerability."

Adobe ColdFusion 9.0.1 CHF1 and earlier, when a web application is configured to use a DBMS, allows remote attackers to obtain potentially sensitive information about the database structure via an id=- query to a .cfm file. NOTE: the vendor disputes the significance of this issue because the Site-wide Error Handler and Debug Output Settings sections of the ColdFusion Lockdown guide explain the requirement for settings that prevent this information disclosure

The xsltGenerateIdFunction function in functions.c in libxslt 1.1.26 and earlier, as used in Google Chrome before 10.0.648.127 and other products, allows remote attackers to obtain potentially sensitive information about heap memory addresses via an XML document containing a call to the XSLT generate-id XPath function.

The webscan component in the Embedded Web Server (EWS) on the HP Photosmart D110 and B110; Photosmart Plus B210; Photosmart Premium C310, Fax All-in-One, and C510; and ENVY 100 D410 printers allows remote attackers to read documents on the scan surface via unspecified vectors.

In Spring Data REST versions 3.4.0 - 3.4.13, 3.5.0 - 3.5.5, and older unsupported versions, HTTP resources implemented by custom controllers using a configured base API path and a controller type-level request mapping are additionally exposed under URIs that can potentially be exposed for unauthorized access depending on the Spring Security configuration.
