Cross-site scripting (XSS) vulnerability in the project module (project.module) in Drupal 4.5 and 4.6 allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors.

Drupal Access Control Bypass

Cross-site request forgery (CSRF) vulnerability in Drupal 6.x before 6.3 allows remote attackers to perform administrative actions via vectors involving deletion of OpenID identities.

The request_path function in includes/bootstrap.inc in Drupal 7.14 and earlier allows remote attackers to obtain sensitive information via the q[] parameter to index.php, which reveals the installation path in an error message.

Cross-site scripting (XSS) vulnerability in Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8 allows remote attackers to inject arbitrary web script or HTML via unknown attack vectors.

Drupal core contains a potential PHP Object Injection vulnerability

Multiple cross-site scripting (XSS) vulnerabilities in Drupal 4.5.0 through 4.5.5 and 4.6.0 through 4.6.3 allow remote attackers to inject arbitrary web script or HTML via various HTML tags and values, such as the (1) legend tag and the value parameter used in (2) label and (3) input tags, possibly due to an incomplete blacklist.

Interpretation conflict in Drupal 4.7.x before 4.7.11 and 5.x before 5.6, when Internet Explorer 6 is used, allows remote attackers to conduct cross-site scripting (XSS) attacks via invalid UTF-8 byte sequences, which are not processed as UTF-8 by Drupal's HTML filtering, but are processed as UTF-8 by Internet Explorer, effectively removing characters from the document and defeating the HTML protection mechanism.

The core BlogAPI module in Drupal 5.x before 5.11 and 6.x before 6.5 does not properly validate unspecified content fields of an internal Drupal form, which allows remote authenticated users to bypass intended access restrictions via modified field values.

Drupal Core Cross-Site Scripting (XSS)

Drupal Core Cross-site scripting vulnerability

The hook_comments API in Drupal 4.7.x before 4.7.8 and 5.x before 5.3 does not pass publication status, which might allow attackers to bypass access restrictions and trigger e-mail with unpublished comments from some modules, as demonstrated by (1) Organic groups and (2) Subscriptions.

Arbitrary PHP code execution in Drupal

Access bypass in Drupal core

Open redirect vulnerability in URL-related API functions in Drupal 6.x before 6.35 and 7.x before 7.35 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via vectors involving the "//" initial sequence.

Drupal core allows Forceful Browsing

Drupal Open Redirect

Cross-site scripting (XSS) vulnerability in Drupal 6.x before 6.28 and 7.x before 7.19, when running with older versions of jQuery that are vulnerable to CVE-2011-4969, allows remote attackers to inject arbitrary web script or HTML via vectors involving unspecified Javascript functions that are used to select DOM elements.

Multiple cross-site request forgery (CSRF) vulnerabilities in forms in Drupal 6.x before 6.4 allow remote attackers to perform unspecified actions via unknown vectors, related to improper token validation for (1) cached forms and (2) forms with AHAH elements.

modules/openid/xrds.inc in Drupal 6.x before 6.33 and 7.x before 7.31 allows remote attackers to have unspecified impact via a crafted DOCTYPE declaration in an XRDS document.
