Unknown vulnerability in the privilege system in Drupal 4.4.0 through 4.6.0, when public registration is enabled, allows remote attackers to gain privileges, due to an "input check" that "is not implemented properly."

Access bypass in Drupal core

Cross-site scripting (XSS) vulnerability in the Image module in Drupal 7.x before 7.24 allows remote authenticated users with certain permissions to inject arbitrary web script or HTML via the description field.

Drupal Core Remote Code Execution Vulnerability

Drupal Settings Tray access bypass

The user module in Drupal 5.x before 5.11 and 6.x before 6.5 might allow remote authenticated users to bypass intended login access rules and successfully login via unknown vectors.

Session fixation vulnerability in Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8 allows remote attackers to gain privileges by tricking a user to click on a URL that fixes the session identifier.

Drupal core Access bypass

Multiple cross-site request forgery (CSRF) vulnerabilities in Drupal 5.x before 5.2 allow remote attackers to (1) delete comments, (2) delete content revisions, and (3) disable menu items as privileged users, related to improper use of HTTP GET and the Forms API.

Cross-site request forgery (CSRF) vulnerability in the Aggregator module in Drupal 6.x before 6.23 and 7.x before 7.11 allows remote attackers to hijack the authentication of unspecified victims for requests that update feeds and possibly cause a denial of service (loss of updates due to rate limit) via unspecified vectors.

Incorrect authorization in Drupal core

Drupal 5.2 and earlier does not properly unset variables when the input data includes a numeric parameter with a value matching an alphanumeric parameter's hash value, which allows remote attackers to execute arbitrary PHP code by invoking the drupal_eval function through a callback parameter to the default URI, as demonstrated by the _menu[callbacks][1][callback] parameter. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Drupal.

Unknown vulnerability in Drupal 4.5.0 through 4.5.3, 4.6.0, and 4.6.1 allows remote attackers to execute arbitrary PHP code via a public comment or posting.

Drupal core third-party PEAR Archive_Tar library is vulnerable to Deserialization of Untrusted Data

Drupal 4.5.x before 4.5.8 and 4.6.x before 4.5.8, when menu.module is used to create a menu item, does not implement access control for the page that is referenced, which might allow remote attackers to access administrator pages.

Drupal access control bypass vulnerability

Cross-site request forgery (CSRF) vulnerability in Drupal 4.6.x before 4.6.10 and 4.7.x before 4.7.4 allows remote attackers to perform unauthorized actions as an arbitrary user via unspecified vectors.

Drupal Users without "Administer comments" can set comment visibility on nodes they can edit

Drupal vulnerable to Cross-site Scripting

Multiple cross-site scripting (XSS) vulnerabilities in the XML parser in Drupal 4.6.x before 4.6.10 and 4.7.x before 4.7.4 allow remote attackers to inject arbitrary web script or HTML via a crafted RSS feed.
