CVE-2024-0698: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in alextselegidis Easy!Appointments
The Easy!Appointments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'easyappointments' shortcode in all versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2024-0698 is a stored cross-site scripting vulnerability in the Easy!Appointments WordPress plugin (up to version 1.3.1). It arises from improper neutralization of input in the 'easyappointments' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No patch or official remediation details are provided in the available data.
Potential Impact
An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages using the vulnerable shortcode. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content when other users view the infected pages. There is no impact on availability reported. No known exploits have been observed in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Easy!Appointments plugin if feasible to prevent exploitation.
