AI Analysis
Technical Summary
CVE-2026-2390 is a stored cross-site scripting vulnerability in the Powerkit plugin for WordPress, specifically in the Lazy Load module's image processing. The vulnerability is due to improper neutralization of input caused by a flawed regex-based HTML attribute parser in the 'content_process_images' function. Authenticated attackers with Contributor-level privileges or higher can exploit this to inject arbitrary web scripts that execute when users access the injected pages. This affects all versions up to and including 3.0.4.
Potential Impact
An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the image processing functionality. These scripts execute in the context of users visiting the affected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect availability but impacts confidentiality and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling the Lazy Load module if feasible.
