Last updated: 16 Jan 2026, 23:25 UTC
This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with cmsimple-xh. We track both calendar-based metrics (using fixed periods) and rolling metrics (using gliding windows) to give you a comprehensive view of security trends and risk evolution. Use these insights to assess risk and plan your patching strategy.
For a broader perspective on cybersecurity threats, explore the comprehensive list of CVEs by vendor and product. Stay updated on critical vulnerabilities affecting major software and hardware providers.
Total cmsimple-xh CVEs: 5
Earliest CVE date: 10 May 2022, 12:15 UTC
Latest CVE date: 23 Dec 2025, 20:15 UTC
Latest CVE reference: CVE-2021-47736
30-day Count (Rolling): 1
365-day Count (Rolling): 3
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): 200.0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 200.0%
Average CVSS: 2.0
Max CVSS: 10.0
Critical CVEs (≥9): 1
| Range | Count |
|---|---|
| 0.0-3.9 | 4 |
| 4.0-6.9 | 0 |
| 7.0-8.9 | 0 |
| 9.0-10.0 | 1 |
These are the five CVEs with the highest CVSS scores for cmsimple-xh, sorted by severity first and recency.
CMSimple_XH 1.7.4 contains an authenticated remote code execution vulnerability in the content editing functionality that allows administrative users to upload malicious PHP files. Attackers with valid credentials can exploit the CSRF token mechanism to create a PHP shell file that enables arbitrary command execution on the server.
A reflected XSS vulnerability exists in CMSimple_XH 1.8's index.php router when attacker-controlled path segments are not sanitized or encoded before being inserted into the generated HTML (navigation links, breadcrumbs, search form action, footer links). An attacker-controlled string placed in the URL path is reflected into multiple HTML elements, allowing execution of arbitrary JavaScript in victims' browsers visiting a crafted URL.
An unauthenticated reflected cross-site scripting vulnerability in the query handling of CMSimpleXH allows remote attackers to inject and execute arbitrary JavaScript in a victim's browser via a crafted request (e.g., a maliciously crafted POST login). Successful exploitation may lead to theft of session cookies, credential disclosure, or other client-side impacts.
CMSimple_XH 1.7.6 allows XSS by uploading a crafted SVG document.
CMSimple_XH 1.7.4 is affected by a remote code execution (RCE) vulnerability. To exploit this vulnerability, an attacker must use the "File" parameter to upload a PHP payload to get a reverse shell from the vulnerable host.
