WordPress BizLibrary plugin <= 1.1 - Reflected Cross Site Scripting (XSS) vulnerability

Published Jan 21, 2025 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed

Description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Matthew BizLibrary bizlibrary allows Reflected XSS.This issue affects BizLibrary: from n/a through <= 1.1.

Analysis

Technical impact

The BizLibrary WordPress plugin contains an improper neutralization of input during page generation that allows attackers to inject malicious script when a victim visits a crafted URL. This is a reflected XSS vulnerability (CWE‑79). The injected script can steal cookies, deface content, or redirect users, compromising any user who accesses the affected page.

Affected Systems

All installations of the Matthew BizLibrary plugin version 1.1 or earlier on WordPress sites. These plugins are commonly used for event or booking features and are deployed on sites that have not yet applied the latest version.

Risk and Exploitability

The CVSS score of 7.1 indicates a moderate severity level. The EPSS score is below 1 %, suggesting that exploitation attempts are expected to be rare and the vulnerability is not currently catalogued in CISA’s KEV. Until a fix is applied, an attacker can embed a malicious script into URLs that are reflected by the plugin, enabling the script to execute in the victim’s browser.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update the BizLibrary plugin to version 1.2 or later, or uninstall the plugin if it is no longer required.
If an upgrade is not immediately possible, block or sanitize the parameters that are reflected by the plugin so that user input is escaped before output.
Add a Content‑Security‑Policy header that restricts inline scripts and disallows unsafe eval to mitigate any residual XSS impact.
