CVE-2025-0862: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in supersaas SuperSaaS – online appointment scheduling
The SuperSaaS – online appointment scheduling plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘after’ parameter in all versions up to, and including, 2.1.12 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is limited to Chromium-based browsers (e.g. Chrome, Edge, Brave).
AI Analysis
Technical Summary
CVE-2025-0862 is a stored cross-site scripting vulnerability in the SuperSaaS WordPress plugin for online appointment scheduling. The issue arises from improper input sanitization and output escaping of the 'after' parameter, allowing authenticated contributors or higher to inject arbitrary web scripts. These scripts execute in Chromium-based browsers when the injected page is accessed. The vulnerability affects all versions up to and including 2.1.12. The CVSS 3.1 base score is 4.9, reflecting network attack vector, high attack complexity, low privileges required, no user interaction, and partial impact on confidentiality and integrity.
Potential Impact
An attacker with Contributor-level or higher privileges can inject persistent malicious scripts into pages via the 'after' parameter. These scripts execute in the context of Chromium-based browsers when other users access the infected pages, potentially leading to data disclosure or session manipulation limited to confidentiality and integrity impacts. There is no impact on availability. The vulnerability does not affect non-Chromium browsers. No known exploits are reported in the wild.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the 'after' parameter if possible. Employ web application firewalls or security plugins that can detect and block XSS payloads as a temporary mitigation.
