Is WordPress safe? Known vulnerabilities and latest version

WordPress 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.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Automattic WordPress wordpress allows DOM-Based XSS.This issue affects WordPress: from n/a through 7.1.

WordPress 6.9.x before 6.9.5 and 7.0.x before 7.0.2 is affected by a REST API batch endpoint route confusion issue which, combined with the author__not_in WP_Query SQL Injection (CVE-2026-60137), could allow an attacker to perform SQL Injection and achieve Remote Code Execution.

WordPress 6.8.x before 6.8.6, 6.9.x before 6.9.5, and 7.0.x before 7.0.2 does not properly sanitise the author__not_in parameter of WP_Query, which could allow SQL Injection when a plugin or theme passes untrusted input to the parameter.

WordPress core is vulnerable to unauthorized access in versions 6.9 through 6.9.1. The Notes feature (block-level collaboration annotations) was introduced in WordPress 6.9 to allow editorial comments directly on posts in the block editor. However, the REST API `create_item_permissions_check()` method in the comments controller did not verify that the authenticated user has `edit_post` permission on the target post when creating a note. This makes it possible for authenticated attackers with Subscriber-level access to create notes on any post, including posts authored by other users, private posts, and posts in any status.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WordPress allows Stored XSS. WordPress core security team is aware of the issue and working on a fix. This is low severity vulnerability that requires an attacker to have Author or higher user privileges to execute the attack vector.This issue affects WordPress: from 6.8 through 6.8.2, from 6.7 through 6.7.3, from 6.6 through 6.6.3, from 6.5 through 6.5.6, from 6.4 through 6.4.6, from 6.3 through 6.3.6, from 6.2 through 6.2.7, from 6.1 through 6.1.8, from 6.0 through 6.0.10, from 5.9 through 5.9.11, from 5.8 through 5.8.11, from 5.7 through 5.7.13, from 5.6 through 5.6.15, from 5.5 through 5.5.16, from 5.4 through 5.4.17, from 5.3 through 5.3.19, from 5.2 through 5.2.22, from 5.1 through 5.1.20, from 5.0 through 5.0.23, from 4.9 through 4.9.27, from 4.8 through 4.8.26, from 4.7 through 4.7.30.

Insertion of Sensitive Information Into Sent Data vulnerability in WordPress allows Retrieve Embedded Sensitive Data. The WordPress Core security team is aware of the issue and is already working on a fix. This is a low-severity vulnerability. Contributor-level privileges required in order to exploit it. This issue affects WordPress: from 6.8 through 6.8.2, from 6.7 through 6.7.3, from 6.6 through 6.6.3, from 6.5 through 6.5.6, from 6.4 through 6.4.6, from 6.3 through 6.3.6, from 6.2 through 6.2.7, from 6.1 through 6.1.8, from 6.0 through 6.0.10, from 5.9 through 5.9.11, from 5.8 through 5.8.11, from 5.7 through 5.7.13, from 5.6 through 5.6.15, from 5.5 through 5.5.16, from 5.4 through 5.4.17, from 5.3 through 5.3.19, from 5.2 through 5.2.22, from 5.1 through 5.1.20, from 5.0 through 5.0.23, from 4.9 through 4.9.27, from 4.8 through 4.8.26, from 4.7 through 4.7.30.

WordPress Core is vulnerable to Stored Cross-Site Scripting via user display names in the Avatar block in various versions up to 6.5.2 due to insufficient output escaping on the display name. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. In addition, it also makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that have the comment block present and display the comment author's avatar.

WordPress 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

Exposure of Sensitive Information to an Unauthorized Actor in WordPress from 6.3 through 6.3.1, from 6.2 through 6.2.2, from 6.1 through 6.13, from 6.0 through 6.0.5, from 5.9 through 5.9.7, from 5.8 through 5.8.7, from 5.7 through 5.7.9, from 5.6 through 5.6.11, from 5.5 through 5.5.12, from 5.4 through 5.4.13, from 5.3 through 5.3.15, from 5.2 through 5.2.18, from 5.1 through 5.1.16, from 5.0 through 5.0.19, from 4.9 through 4.9.23, from 4.8 through 4.8.22, from 4.7 through 4.7.26, from 4.6 through 4.6.26, from 4.5 through 4.5.29, from 4.4 through 4.4.30, from 4.3 through 4.3.31, from 4.2 through 4.2.35, from 4.1 through 4.1.38.

WordPress 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.
