CVE-2026-15345: CWE-862 Missing Authorization in shortpixel ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization
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.
AI Analysis
Technical Summary
CVE-2026-15345 is an authorization bypass vulnerability (CWE-862) in the ShortPixel Adaptive Images WordPress plugin. The plugin fails to properly verify user authorization before allowing modification of configuration settings. This flaw allows authenticated users with low privileges (subscriber-level and above) to alter settings of third-party plugins such as ShortPixel Image Optimizer, Autoptimize, WP Rocket, Imagify, and LiteSpeed Cache, as well as the ShortPixel plugin's API key and account binding. The impact on third-party plugins is contingent on their installation. The vulnerability affects all versions up to and including 3.11.5.
Potential Impact
The vulnerability allows low-privileged authenticated users to modify configuration settings of multiple third-party plugins and the ShortPixel plugin itself. This could lead to unauthorized changes in plugin behavior or API key misuse. There is no direct confidentiality or availability impact reported. Exploitation requires the attacker to have at least subscriber-level access and the presence of the targeted third-party plugins.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict subscriber-level access where possible and monitor for unauthorized configuration changes in affected plugins.
