CVE-2023-49850

Vulnerability

Overview The WP Simple HTML Sitemap plugin for WordPress versions through 2.7 suffers from a missing authorization vulnerability [1]. This broken access control issue means that certain functions lack proper permission checks, allowing users without the necessary privileges to execute them.

Exploitation

An unauthenticated attacker can exploit this by sending specially crafted requests to the vulnerable endpoints [1]. No authentication or special conditions are required, increasing the attack surface for mass exploitation campaigns.

Impact

Successful exploitation enables an attacker to perform actions intended only for authorized users, such as modifying sitemap settings or accessing restricted data [1]. Although the severity is rated medium (CVSS 5.3), the ease of exploitation makes it a target for automated attacks.

Mitigation

The vulnerability has been addressed in version 2.8 of the plugin [1]. Users are strongly advised to update immediately. Patchstack recommends enabling auto-updates for vulnerable plugins to prevent such issues [1].
