CVE-2026-34563: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in ci4-cms-erp ci4ms
CI4MS versions prior to 0. 31. 0. 0 contain a stored blind cross-site scripting (XSS) vulnerability due to improper sanitization of user input in backup uploads and metadata processing. An attacker can inject malicious JavaScript into backup filenames, which is then rendered unsafely in backup management views. This vulnerability has been patched in version 0. 31. 0. 0.
AI Analysis
Technical Summary
The CI4MS CMS, based on CodeIgniter 4, improperly neutralizes user input during web page generation related to backup uploads and metadata. Specifically, backup filenames can contain malicious JavaScript injected via an uploaded SQL backup file (xss.sql) that uses SQL functionality to insert the payload server-side. This stored payload is later rendered without proper output encoding in multiple backup management views, resulting in a stored blind XSS vulnerability. The issue affects versions prior to 0.31.0.0 and has been fixed in that version.
Potential Impact
Successful exploitation allows an attacker with at least low privileges to inject and store malicious JavaScript code that executes in the context of users viewing backup management pages. This can lead to high confidentiality impact, limited integrity impact, and limited availability impact. The CVSS score is 9.1 (critical), indicating a severe risk if exploited.
Mitigation Recommendations
Upgrade to ci4ms version 0.31.0.0 or later, where this vulnerability has been patched. No other mitigation actions are specified or required once the patch is applied.
