Summary
by MITRE • 03/16/2026
Raytha CMS is vulnerable to Stored XSS via FieldValues[1].Value parameter in post editing functionality. Authenticated attacker with permissions to edit posts can inject arbitrary HTML and JS into website, which will be rendered/executed when visiting edited page.
This issue was fixed in version 1.4.6.

Raytha CMS version 1.4.5 and earlier contains a critical stored cross-site scripting vulnerability in its post editing functionality that allows authenticated attackers with sufficient permissions to inject malicious code into the system. The vulnerability specifically resides in the FieldValues[1].Value parameter processing within the post editing endpoint, where user input is not properly sanitized or validated before being stored in the database and subsequently rendered in web pages. This flaw enables attackers to execute arbitrary JavaScript code in the context of other users' browsers when they visit pages containing the maliciously injected content.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding mechanisms within the CMS's content management interface. When an authenticated user with editing privileges modifies a post and submits data containing malicious scripts in the FieldValues[1].Value parameter, the system fails to properly escape or filter special characters that could be interpreted as HTML or JavaScript markup. The stored payload persists in the database and executes whenever the affected page is rendered, creating a classic stored XSS attack vector that can be exploited against any user who accesses the compromised content.
The operational impact of this vulnerability is significant as it provides attackers with persistent access to user sessions and potentially sensitive data. An attacker could inject scripts that steal cookies, redirect users to malicious sites, or perform actions on behalf of authenticated users. This vulnerability affects the integrity and confidentiality of the CMS's content management system, potentially leading to unauthorized access to administrative functions, data exfiltration, or further compromise of the web application environment. The attack requires only minimal privileges to exploit, making it particularly dangerous in environments where multiple users have editing capabilities.
The vulnerability aligns with CWE-79 which defines Cross-Site Scripting as a weakness that allows attackers to inject malicious scripts into web applications. From an adversarial perspective, this flaw maps to attack techniques within the MITRE ATT&CK framework under T1059.007 for Command and Scripting Interpreter and T1566 for Phishing, as attackers could use this vulnerability to deliver malicious payloads through compromised content. The attack chain typically involves gaining access to a legitimate user account with editing permissions, crafting malicious payloads targeting the specific parameter, submitting the content, and waiting for other users to view the compromised pages.
Organizations using Raytha CMS should immediately upgrade to version 1.4.6 or later to remediate this vulnerability. Additionally, administrators should implement proper input validation and output encoding mechanisms throughout the application, particularly in content management interfaces. Regular security audits of user permissions and access controls should be conducted to minimize the attack surface. The implementation of Content Security Policy headers can provide an additional layer of defense against XSS attacks, while web application firewalls can help detect and block malicious payloads attempting to exploit this vulnerability. Security awareness training for content editors should emphasize the importance of not including untrusted content in editable fields, as this vulnerability demonstrates how even legitimate users can become vectors for attack through the exploitation of proper input validation mechanisms.
