CVE-2026-1183: Botble Products XSS Vulnerability

CVE-2026-1183 Overview

CVE-2026-1183 is an HTML injection vulnerability affecting multiple Botble products including TransP, Athena, Martfury, and Homzen. The vulnerability exists due to a lack of proper validation of user input when processing requests to the /search endpoint via the q parameter. This allows attackers to inject arbitrary HTML content into web pages served by affected applications.

Critical Impact

Attackers can inject malicious HTML content into search results, potentially leading to phishing attacks, content spoofing, and session manipulation affecting end users of affected Botble products.

Affected Products

• Botble TransP
• Botble Athena
• Botble Martfury
• Botble Homzen

Technical Details for CVE-2026-1183

Vulnerability Analysis

This HTML injection vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly associated with cross-site scripting and HTML injection issues. The vulnerability resides in the search functionality of multiple Botble e-commerce and content management products.

When a user submits a search query through the /search endpoint, the application fails to properly sanitize the q parameter before rendering it in the response HTML. This improper input validation allows an attacker to craft malicious requests containing HTML markup that gets reflected back to users without proper encoding or escaping.

The network-based attack vector requires user interaction, meaning victims must be tricked into clicking a crafted link or visiting a malicious page that triggers the vulnerable endpoint. While the impact on confidentiality and integrity of the vulnerable system itself is limited, the vulnerability can affect the integrity of the downstream user interface through content manipulation.

Root Cause

The root cause of this vulnerability is insufficient input sanitization in the search functionality. The affected Botble products do not implement proper output encoding or input validation when processing the q parameter in search requests. Specifically, HTML special characters such as <, >, ", and & are not properly escaped before being rendered in the search results page, allowing HTML tags to be interpreted by the browser.

Attack Vector

The attack is conducted over the network by crafting a malicious URL that includes HTML injection payloads in the q parameter of the /search endpoint. An attacker can distribute these crafted links through phishing emails, social media, or by embedding them in other websites.

When a victim clicks the malicious link, the injected HTML content is rendered in the context of the legitimate Botble-powered website. This can be leveraged to display fake content, create convincing phishing forms that appear to be part of the legitimate site, or manipulate the visual presentation of the page to mislead users.

The vulnerability requires user interaction as victims must actively visit the crafted URL for the attack to succeed. For detailed technical information, see the INCIBE Security Notice.

Detection Methods for CVE-2026-1183

Indicators of Compromise

• Unusual search queries containing HTML tags or encoded HTML characters in server logs
• Access logs showing requests to /search endpoint with suspicious q parameter values containing <, >, or encoded variants
• User reports of unexpected content appearing on search results pages

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block requests containing HTML tags in the q parameter
• Monitor application logs for search queries containing potentially malicious payloads such as <script>, <iframe>, <form>, or other HTML elements
• Deploy runtime application self-protection (RASP) solutions to detect injection attempts at the application layer
• Conduct regular security scanning of Botble installations using web vulnerability scanners

Monitoring Recommendations

• Enable detailed logging for the /search endpoint to capture full query strings
• Set up alerts for unusual patterns in search parameter values, particularly those containing angle brackets or URL-encoded HTML entities
• Monitor for spikes in search requests that may indicate automated exploitation attempts
• Review user session activity following visits to search pages for signs of credential theft or session manipulation

How to Mitigate CVE-2026-1183

Immediate Actions Required

• Implement server-side input validation to reject or sanitize HTML characters in search parameters
• Apply output encoding to all user-supplied data before rendering in HTML responses
• Deploy Content Security Policy (CSP) headers to reduce the impact of any successful HTML injection
• Consider implementing a Web Application Firewall (WAF) rule to filter requests containing HTML tags in the search parameter

Patch Information

At the time of publication, consult the INCIBE Security Notice for the latest information on vendor patches and updates for affected Botble products. Contact the Botble vendor directly for specific patch availability for TransP, Athena, Martfury, and Homzen products.

Workarounds

• Implement a custom input sanitization filter at the web server or reverse proxy level to strip HTML tags from the q parameter
• Deploy a WAF rule to block requests to /search containing angle brackets or common HTML injection patterns
• Consider temporarily disabling the search functionality if exploitation is actively occurring until a proper fix can be applied
• Implement rate limiting on the search endpoint to slow down automated exploitation attempts

# Example nginx configuration to sanitize search parameter
location /search {
    # Block requests containing HTML tags in query string
    if ($arg_q ~* "<[^>]*>") {
        return 403;
    }
    
    # Additional CSP header for defense in depth
    add_header Content-Security-Policy "default-src 'self'; script-src 'self';" always;
    
    proxy_pass http://backend;
