AI Analysis
Technical Summary
CVE-2025-9519 is a remote code execution vulnerability in the kleor Easy Timer WordPress plugin affecting all versions up to 4.2.1. The issue arises from insufficient validation and control over shortcode attributes, allowing authenticated users with Editor or higher privileges to inject and execute arbitrary code on the server hosting the plugin. This vulnerability is classified under CWE-94 (Improper Control of Generation of Code). The CVSS v3.1 base score is 7.2, indicating a high severity with network attack vector, low attack complexity, and requiring high privileges but no user interaction.
Potential Impact
Successful exploitation allows an attacker with Editor-level access or higher to execute arbitrary code on the server, potentially leading to full compromise of the affected WordPress site. This can result in unauthorized data access, site defacement, or further pivoting within the hosting environment. The vulnerability affects confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Editor-level and higher privileges to trusted users only. Consider disabling or removing the Easy Timer plugin if possible to mitigate risk. Monitor for updates from the vendor or WordPress plugin repository for an official patch.
