The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.11.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify configuration options of third-party plugins including ShortPixel Image Optimizer, Autoptimize, WP Rocket, Imagify, and LiteSpeed Cache, as well as the plugin's own API key and account binding. Exploitation requires the respective third-party plugins to be installed, as the impact against those plugins' settings is only reachable when those plugins are present.

The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 7.8.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A comment payload crafted exclusively from decimal numeric character references (e.g. ", <, >) placed inside an allowed element such as <code> bypasses WordPress's wp_kses sanitization, as kses does not treat a data-settings="..." substring within text content as an HTML attribute, allowing the malicious payload to reach the vulnerable function. For this to be exploitable, the site must allow users with previously approved comments to write new comments, and the require_name_email setting must be disabled.

The LiteSpeed Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via crafted `` tag attributes in all versions up to, and including, 7.7. This is due to a

Security vulnerabilities tied to ea-nginx-njs(CVE-2026-8711) and ea-memcached16(CVE-2026-47783, CVE-2026-47784) have been discovered.

An upstream vulnerability was recently reported for Unbound that affects supported cPanel & WHM versions 126 and higher.

A security vulnerability was found in the plugin provided by LiteSpeed that allowed unauthorized root access to the server.

A vulnerability has been reported that currently affects cPanel & WHM versions 132 and higher.

This security release addresses vulnerabilities across multiple versions of cPanel & WHM, including fixes for several vulnerabilities rated up to High severity.

It was found that SSL verification was not fully enforced in the DNS Cluster system, which could allow for a malicious server to man-in-the-middle the request and capture credentials. This affects cPanel & WHM versions 126 and higher.

It was found that a low-privilege team user (role=default) can escalate to the owner account's full capabilities through the use of certain UAPI modules. This affects cPanel & WHM versions 110 and higher.

It was found that, as part of the sqloptimizer script, it was possible that a created SQL query could be injected with arbitrary SQL queries. This affects all cPanel & WHM versions.

Through a combination of incorrect dropping of privileges and insufficient path filtering, it was possible to read arbitrary files via certain cpdavd endpoints. This affects cPanel & WHM versions 120 and higher.

The vulnerability, tracked as CVE-2026-45185, aka Dead.Letter, has been described as a use-after-free vulnerability in Exim's binary data transmission (BDAT) message body parsing when a TLS connection is handled by GnuTLS.

A Perl code injection method was found in the create_user API call, relating to the plugin parameter.
