LiteSpeed CVE-2026-15345

LiteSpeed

Was das unter einer SharedLicense-Lizenz bedeutet

Your SharedLicense license itself is not affected — this is a vulnerability in LiteSpeed software, not in licensing. Licenses continue to work during and after the update; there is no need to re-issue or re-activate anything. If you resell LiteSpeed under your own brand, patch client servers too — unpatched installs put your reputation at risk, not your license.

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.
