At a glance
CVE-2026-57762 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Lasso Lite WordPress plugin, affecting versions <= 152. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 153; sites on affected versions should update now. Disclosed July 2026, reported by Athiwat Tiprasaharn (Jitlada).
Vulnerability Overview
The Simple URLs – Link Cloaking, Product Displays, and Affiliate Link Management plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 152 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Lasso Lite <= 152 takes an account at Author level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Lasso Lite the fix is 153: builds <= 152 are affected, anything from 153 onward is not.
Remediation
Update to version 153, or a newer patched version
How does WordSec protect against this?
An attacker needs Author access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Lasso Lite 153 closes this, and updating the plugin is the step that ends it.
