WordPress version <4.9 contains a CWE-20 Input Validation vulnerability in thumbnail processing that can result in remote code execution. This attack appears to be exploitable via thumbnail upload by an authenticated user and may require additional plugins in order to be exploited however this has not been confirmed at this time. This issue appears to have been partially, but not completely fixed in WordPress 4.9

WordPress before 4.9.9 and 5.x before 5.0.1 allows remote code execution because an _wp_attached_file Post Meta entry can be changed to an arbitrary string, such as one ending with a .jpg?file.php substring. An attacker with author privileges can execute arbitrary code by uploading a crafted image containing PHP code in the Exif metadata. Exploitation can leverage CVE-2019-8943.

SQL injection vulnerability in options.php in WordPress 2.2.1 allows remote authenticated administrators to execute arbitrary SQL commands via the page_options parameter to (1) options-general.php, (2) options-writing.php, (3) options-reading.php, (4) options-discussion.php, (5) options-privacy.php, (6) options-permalink.php, (7) options-misc.php, and possibly other unspecified components.

Unrestricted file upload vulnerability in (1) wp-app.php and (2) app.php in WordPress 2.2.1 and WordPress MU 1.2.3 allows remote authenticated users to upload and execute arbitrary PHP code via unspecified vectors, possibly related to the wp_postmeta table and the use of custom fields in normal (non-attachment) posts. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2007-3543.

wp-login.php in WordPress allows remote attackers to redirect authenticated users to other websites and potentially obtain sensitive information via the redirect_to parameter.

SQL injection vulnerability in xmlrpc (xmlrpc.php) in WordPress 2.1.2, and probably earlier, allows remote authenticated users to execute arbitrary SQL commands via a string parameter value in an XML RPC mt.setPostCategories method call, related to the post_id variable.

Multiple SQL injection vulnerabilities in the Mingle Forum plugin 1.0.32.1 and other versions before 1.0.33 for WordPress might allow remote authenticated users to execute arbitrary SQL commands via the (1) memberid or (2) groupid parameters in a removemember action or (3) id parameter to fs-admin/fs-admin.php, or (4) edit_forum_id parameter in an edit_save_forum action to fs-admin/wpf-edit-forum-group.php.

WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Due to lack of proper sanitization in one of the classes, there's potential for unintended SQL queries to be executed. This has been patched in WordPress version 5.8.3. Older affected versions are also fixed via security release, that go back till 4.1.34. We strongly recommend that you keep auto-updates enabled. There are no known workarounds for this issue.

WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. On a multisite, users with Super Admin role can bypass explicit/additional hardening under certain conditions through object injection. This has been patched in WordPress version 5.8.3. Older affected versions are also fixed via security release, that go back till 3.7.37. We strongly recommend that you keep auto-updates enabled. There are no known workarounds for this issue.

In WordPress 4.9.7, plugins uploaded via the admin area are not verified as being ZIP files. This allows for PHP files to be uploaded. Once a PHP file is uploaded, the plugin extraction fails, but the PHP file remains in a predictable wp-content/uploads location, allowing for an attacker to then execute the file. This represents a security risk in limited scenarios where an attacker (who does have the required capabilities for plugin uploads) cannot simply place arbitrary PHP code into a valid plugin ZIP file and upload that plugin, because a machine's wp-content/plugins directory permissions were set up to block all new plugins.

WordPress through 4.9.6 allows Author users to execute arbitrary code by leveraging directory traversal in the wp-admin/post.php thumb parameter, which is passed to the PHP unlink function and can delete the wp-config.php file. This is related to missing filename validation in the wp-includes/post.php wp_delete_attachment function. The attacker must have capabilities for files and posts that are normally available only to the Author, Editor, and Administrator roles. The attack methodology is to delete wp-config.php and then launch a new installation process to increase the attacker's privileges.

wp-admin/user-new.php in WordPress before 4.9.1 sets the newbloguser key to a string that can be directly derived from the user ID, which allows remote attackers to bypass intended access restrictions by entering this string.

wp-admin/options.php in WordPress MU before 1.3.2, and WordPress 2.3.2 and earlier, does not properly validate requests to update an option, which allows remote authenticated users with manage_options and upload_files capabilities to execute arbitrary code by uploading a PHP script and adding this script's pathname to active_plugins.

WordPress before 2.6.2 does not properly handle MySQL warnings about insertion of username strings that exceed the maximum column width of the user_login column, and does not properly handle space characters when comparing usernames, which allows remote attackers to change an arbitrary user's password to a random value by registering a similar username and then requesting a password reset, related to a "SQL column truncation vulnerability." NOTE: the attacker can discover the random password by also exploiting CVE-2008-4107.

In WordPress before 4.9.9 and 5.x before 5.0.1, authors could bypass intended restrictions on post types via crafted input.

The get_allowed_mime_types function in wp-includes/functions.php in WordPress before 3.6.1 does not require the unfiltered_html capability for uploads of .htm and .html files, which might make it easier for remote authenticated users to conduct cross-site scripting (XSS) attacks via a crafted file.

moxieplayer.as in Moxiecode moxieplayer, as used in the TinyMCE Media plugin in WordPress before 3.5.2 and other products, does not consider the presence of a # (pound sign) character during extraction of the QUERY_STRING, which allows remote attackers to pass arbitrary parameters to a Flash application, and conduct content-spoofing attacks, via a crafted string after a ? (question mark) character.

wp-includes/http.php in WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 allows remote attackers to conduct server-side request forgery (SSRF) attacks by referring to a 127.0.0.0/8 resource.

WordPress through 4.8.2, when domain-based flashmediaelement.swf sandboxing is not used, allows remote attackers to conduct cross-domain Flash injection (XSF) attacks by leveraging code contained within the wp-includes/js/mediaelement/flashmediaelement.swf file.

wp_kses_bad_protocol in wp-includes/kses.php in WordPress before 5.3.1 mishandles the HTML5 colon named entity, allowing attackers to bypass input sanitization, as demonstrated by the javascript&colon; substring.

WP-Syntax plugin 0.9.1 and earlier for Wordpress, with register_globals enabled, allows remote attackers to execute arbitrary PHP code via the test_filter[wp_head] array parameter to test/index.php, which is used in a call to the call_user_func_array function.

WordPress 2.7.1 places the username of a post's author in an HTML comment, which allows remote attackers to obtain sensitive information by reading the HTML source.

The make_clickable function in wp-includes/formatting.php in WordPress before 3.1.1 does not properly check URLs before passing them to the PCRE library, which allows remote attackers to cause a denial of service (crash) via a comment with a crafted URL that triggers many recursive calls.

Unrestricted file upload vulnerability in upload.php in PhotoPost vBGallery 2.4.2 allows remote authenticated users to execute arbitrary code by uploading a file with an executable extension followed by a safe extension, then accessing it via a direct request to the file in a certain path. NOTE: this may be the same vulnerability as CVE-2008-0251, but this is not clear due to lack of details from the vendor.
