CVE-2024-11804: 
WordPress vulnerability analysis and mitigation

The Planaday API plugin for WordPress contains a Reflected Cross-Site Scripting vulnerability (CVE-2024-11804) that affects all versions up to and including 11.4. The vulnerability was disclosed on December 12, 2024, and stems from insufficient input sanitization and output escaping in the 'tab' parameter (NVD).

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) with a CVSS v3.1 base score of 6.1 (Medium). The attack vector is network-based (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), and needs user interaction (UI:R). The scope is changed (S:C) with low confidentiality and integrity impact (C:L, I:L) and no availability impact (A:N) (NVD, Wordfence).

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts that execute when users perform specific actions, such as clicking on a malicious link. This could lead to the compromise of user sessions and potential theft of sensitive information (NVD).

Users should update their Planaday API WordPress plugin to a version newer than 11.4 once available. In the meantime, website administrators should implement additional security controls and monitor for suspicious activities targeting the 'tab' parameter (NVD).
