There are 9 open security issues in bookworm.
5 important issues:
- CVE-2019-8943:
WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An attacker (who has privileges to crop an image) can write the output image to an arbitrary directory via a filename containing two image extensions and ../ sequences, such as a filename ending with the .jpg?/../../file.jpg substring.
- CVE-2023-5692:
WordPress Core is vulnerable to Sensitive Information Exposure in versions up to, and including, 6.4.3 via the redirect_guess_404_permalink function. This can allow unauthenticated attackers to expose the slug of a custom post whose 'publicly_queryable' post status has been set to 'false'.
- CVE-2024-4439:
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.
- CVE-2024-6307:
WordPress Core is vulnerable to Stored Cross-Site Scripting via the HTML API in various versions prior to 6.5.5 due to insufficient input sanitization and output escaping on URLs. 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.
- CVE-2024-31111:
Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Automattic WordPress allows Stored XSS.This issue affects WordPress: from 6.5 through 6.5.4, from 6.4 through 6.4.4, from 6.3 through 6.3.4, from 6.2 through 6.2.5, from 6.1 through 6.1.6, from 6.0 through 6.0.8, from 5.9 through 5.9.9.
4 issues left for the package maintainer to handle:
- CVE-2012-6707:
(postponed; to be fixed through a stable update)
WordPress through 4.8.2 uses a weak MD5-based password hashing algorithm, which makes it easier for attackers to determine cleartext values by leveraging access to the hash values. NOTE: the approach to changing this may not be fully compatible with certain use cases, such as migration of a WordPress site from a web host that uses a recent PHP version to a different web host that uses PHP 5.2. These use cases are plausible (but very unlikely) based on statistics showing widespread deployment of WordPress with obsolete PHP versions.
- CVE-2022-3590:
(needs triaging)
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.
- CVE-2018-14028:
(postponed; to be fixed through a stable update)
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.
- TEMP-1036689-1CA7FB:
(postponed; to be fixed through a stable update)
