CVESeverityCVSSPublishedSummary
CVE-2020-36326CRITICAL9.8Apr 28, 2021PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname. NOTE: this is similar to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in which UNC pathnames were always considered unreadable by PHPMailer, even in safe contexts. As an unintended side effect, this fix eliminated the code that blocked addAttachment exploitation.
CVE-2018-19296HIGH8.8Nov 16, 2018PHPMailer before 5.2.27 and 6.x before 6.0.6 is vulnerable to an object injection attack.
CVE-2026-119977HIGH8.1Oct 31, 2026WordPress Core is vulnerable to Remote Code Execution in versions 4.7 through 7.1.3. This is due to predictable, web-accessible staging paths used during full-package core upgrades. This makes it possible for unauthenticated attackers to execute code on the server during the upgrade window.
CVE-2026-87902HIGH8.1Sep 22, 2026An unauthenticated attacker can make `get_page_template()` page-template resolution include a chosen readable local `.php` file outside the active theme directories. If relevant pre-conditions for both the server and the active theme are met, this can lead to RCE.
CVE-2021-44223HIGH8.1Nov 25, 2021WordPress before 5.8 lacks support for the Update URI plugin header. This makes it easier for remote attackers to execute arbitrary code via a supply-chain attack against WordPress installations that use any plugin for which the slug satisfies the naming constraints of the WordPress.org Plugin Directory but is not yet present in that directory.
CVE-2022-21662HIGH8.0Jan 6, 2022WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Low-privileged authenticated users (like author) in WordPress core are able to execute JavaScript/perform stored XSS attack, which can affect high-privileged users. 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 workarou
CVE-2022-21661HIGH8.0Jan 6, 2022WordPress is a free and open-source content management system written in PHP and paired with a MariaDB database. Due to improper sanitization in WP_Query, there can be cases where SQL injection is possible through plugins or themes that use it in a certain way. 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 vul
CVE-2024-31210HIGH7.6Apr 4, 2024WordPress is an open publishing platform for the Web. It's possible for a file of a type other than a zip file to be submitted as a new plugin by an administrative user on the Plugins -> Add New -> Upload Plugin screen in WordPress. If FTP credentials are requested for installation (in order to move the file into place outside of the `uploads` directory) then the uploaded file remains temporary available in the Media Library despite it not being allowed. If the `DISALLOW_FILE_EDIT` constant is s
CVE-2021-39201HIGH7.6Sep 9, 2021WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. ### Impact The issue allows an authenticated but low-privileged user (like contributor/author) to execute XSS in the editor. This bypasses the restrictions imposed on users who do not have the permission to post `unfiltered_html`. ### Patches This has been patched in WordPress 5.8, and will be pushed to older versions via minor releases (automatic updates). It's strongly reco
CVE-2011-5216HIGH7.5Oct 25, 2012SQL injection vulnerability in ajax.php in SCORM Cloud For WordPress plugin before 1.0.7 for WordPress allows remote attackers to execute arbitrary SQL commands via the active parameter. NOTE: some of these details are obtained from third party information.
CVE-2022-21664HIGH7.4Jan 6, 2022WordPress 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.
CVE-2021-29447HIGH7.1Apr 15, 2021Wordpress is an open source CMS. A user with the ability to upload files (like an Author) can exploit an XML parsing issue in the Media Library leading to XXE attacks. This requires WordPress installation to be using PHP 8. Access to internal files is possible in a successful XXE attack. This has been patched in WordPress version 5.7.1, along with the older affected versions via a minor release. We strongly recommend you keep auto-updates enabled.
CVE-2007-2627MEDIUM6.8May 11, 2007Cross-site scripting (XSS) vulnerability in sidebar.php in WordPress, when custom 404 pages that call get_sidebar are used, allows remote attackers to inject arbitrary web script or HTML via the query string (PHP_SELF), a different vulnerability than CVE-2007-1622.
CVE-2022-21663MEDIUM6.6Jan 6, 2022WordPress 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.
CVE-2021-29450MEDIUM6.5Apr 15, 2021Wordpress is an open source CMS. One of the blocks in the WordPress editor can be exploited in a way that exposes password-protected posts and pages. This requires at least contributor privileges. This has been patched in WordPress 5.7.1, along with the older affected versions via minor releases. It's strongly recommended that you keep auto-updates enabled to receive the fix.
CVE-2022-43500MEDIUM6.1Dec 5, 2022Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7.
CVE-2022-43497MEDIUM6.1Dec 5, 2022Cross-site scripting vulnerability in WordPress versions prior to 6.0.3 allows a remote unauthenticated attacker to inject an arbitrary script. The developer also provides new patched releases for all versions since 3.7.
CVE-2022-3590MEDIUM5.9Dec 14, 2022WordPress is affected by an unauthenticated blind SSRF in the pingback feature. Because of a TOCTOU race condition between the validation checks and the HTTP request, attackers can reach internal hosts that are explicitly forbidden.
CVE-2023-2745MEDIUM5.4May 17, 2023WordPress Core is vulnerable to Directory Traversal in versions up to, and including, 6.2, via the ‘wp_lang’ parameter. This allows unauthenticated attackers to access and load arbitrary translation files. In cases where an attacker is able to upload a crafted translation file onto the site, such as via an upload form, this could be also used to perform a Cross-Site Scripting attack.
CVE-2023-5561MEDIUM5.3Oct 16, 2023WordPress does not properly restrict which user fields are searchable via the REST API, allowing unauthenticated attackers to discern the email addresses of users who have published public posts on an affected website via an Oracle style attack
