CVE-2025-62153

Vulnerability

Overview

The Quick Interest Slider plugin for WordPress (versions n/a through 3.1.7) suffers from a Missing Authorization vulnerability [1]. This bug falls under the category of 'Broken Access Control' [1], meaning the plugin fails to properly validate that a user has the necessary permissions before executing certain functions. This can lead to unprivileged users performing actions that should be reserved for higher-privileged roles [1].

Attack

Vector and Exploitation

Exploitation does not require authentication as a high-privileged user; instead, the missing authorization check allows an attacker with minimal or no privileges to trigger unauthorized functionality [1]. The attack surface is broad, as the issue affects all sites running the vulnerable plugin versions, regardless of site size or popularity [1]. These types of vulnerabilities are known to be targeted in mass-exploit campaigns [1].

Impact

An attacker successfully exploiting this flaw can execute certain higher-privileged actions that the plugin's functions allow, circumventing the intended access controls [1]. The precise capabilities gained depend on the specific functions protected only by the missing authorization check, but they could include modifying content, configuration, or other sensitive operations.

Mitigation

Users are strongly advised to update the Quick Interest Slider plugin to a patched version (3.1.8 or later) as an immediate action [1]. If an update is not possible, contacting a hosting provider or web developer for assistance is recommended [1]. The vulnerability has a CVSS v3 base score of 5.3 (Medium Severity), reflecting a significant but not critical risk [1].
