Title

GetSimpleCMS-CE < 3.3.22 Stored XSS via components.php

Summary

GetSimpleCMS Community Edition (CE) version 3.3.16 contains a stored cross-site scripting (XSS) vulnerability in the Theme to Components functionality within components.php. User-supplied input provided to the "slug" field of a component is stored without proper output encoding. While other fields are sanitized using safe_slash_html(), the slug parameter is written to XML and later rendered in the administrative interface without sanitation, resulting in persistent execution of arbitrary JavaScript. An authenticated administrator can inject malicious script content that executes whenever the affected Components page is viewed by any authenticated user, enabling session hijacking, unauthorized administrative actions, and persistent compromise of the CMS administrative interface.

Severity ?

4.8 (Medium)

CVE-2026-27146 (GCVE-0-2026-27146)

Vulnerability from nvd – Published: 2026-02-20 23:10 – Updated: 2026-02-20 23:10

Title

GetSimple CMS: Cross-Site Request Forgery (CSRF) in File Upload Allows Arbitrary Uploads

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS do not implement CSRF protection on the administrative file upload endpoint. As a result, an attacker can craft a malicious web page that silently triggers a file upload request from an authenticated victim’s browser. The request is accepted without requiring a CSRF token or origin validation. This allows an attacker to upload arbitrary files to the application without the victim’s knowledge or consent. In order to exploit this vulnerability, the victim must be authenticated to GetSimple CMS (e.g., admin user), and visit an attacker-controlled webpage. This issue does not have a fix at the time of publication.

Severity ?

CVE-2026-27161 (GCVE-0-2026-27161)

Vulnerability from nvd – Published: 2026-02-20 23:19 – Updated: 2026-02-20 23:19

Title

Unauthenticated Information Disclosure via .htaccess Reliance in Sensitive Directories

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS rely on .htaccess files to restrict access to sensitive directories such as /data/ and /backups/. If Apache AllowOverride is disabled (common in hardened or shared hosting environments), these protections are silently ignored, allowing unauthenticated attackers to list and download sensitive files including authorization.xml, which contains cryptographic salts and API keys. This issue does not have a fix at the time of publication.

Severity ?

8.7 (High)

GetSimple CMS: Stored Cross-Site Scripting (XSS) via SVG File Upload (Authenticated)

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS are vulnerable to XSS through SVG file uploads. Authenticated users can upload SVG files via the administrative upload functionality, but they are not properly sanitized or restricted, allowing an attacker to embed malicious JavaScript. When the uploaded SVG file is accessed, the script executes in the browser. This issue does not have a fix at the time of publication.

Severity ?

CVE-2026-26351 (GCVE-0-2026-26351)

Vulnerability from cvelistv5 – Published: 2026-02-24 22:05 – Updated: 2026-02-24 22:05

Title

GetSimpleCMS-CE < 3.3.22 Stored XSS via components.php

Summary

GetSimpleCMS Community Edition (CE) version 3.3.16 contains a stored cross-site scripting (XSS) vulnerability in the Theme to Components functionality within components.php. User-supplied input provided to the "slug" field of a component is stored without proper output encoding. While other fields are sanitized using safe_slash_html(), the slug parameter is written to XML and later rendered in the administrative interface without sanitation, resulting in persistent execution of arbitrary JavaScript. An authenticated administrator can inject malicious script content that executes whenever the affected Components page is viewed by any authenticated user, enabling session hijacking, unauthorized administrative actions, and persistent compromise of the CMS administrative interface.

Severity ?

4.8 (Medium)

Title

Unauthenticated Information Disclosure via .htaccess Reliance in Sensitive Directories

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS rely on .htaccess files to restrict access to sensitive directories such as /data/ and /backups/. If Apache AllowOverride is disabled (common in hardened or shared hosting environments), these protections are silently ignored, allowing unauthenticated attackers to list and download sensitive files including authorization.xml, which contains cryptographic salts and API keys. This issue does not have a fix at the time of publication.

Severity ?

GetSimple CMS: Stored Cross-Site Scripting (XSS) via SVG File Upload (Authenticated)

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS are vulnerable to XSS through SVG file uploads. Authenticated users can upload SVG files via the administrative upload functionality, but they are not properly sanitized or restricted, allowing an attacker to embed malicious JavaScript. When the uploaded SVG file is accessed, the script executes in the browser. This issue does not have a fix at the time of publication.

CVE-2026-27146 (GCVE-0-2026-27146)

Vulnerability from cvelistv5 – Published: 2026-02-20 23:10 – Updated: 2026-02-20 23:10

Title

GetSimple CMS: Cross-Site Request Forgery (CSRF) in File Upload Allows Arbitrary Uploads

Summary

GetSimple CMS is a content management system. All versions of GetSimple CMS do not implement CSRF protection on the administrative file upload endpoint. As a result, an attacker can craft a malicious web page that silently triggers a file upload request from an authenticated victim’s browser. The request is accepted without requiring a CSRF token or origin validation. This allows an attacker to upload arbitrary files to the application without the victim’s knowledge or consent. In order to exploit this vulnerability, the victim must be authenticated to GetSimple CMS (e.g., admin user), and visit an attacker-controlled webpage. This issue does not have a fix at the time of publication.

Severity ?

7.1 (High)
