DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in devfelixmoira Knowledge Base – Knowledge Base Maker allows Stored XSS. This issue affects Knowledge Base – Knowledge Base Maker: from n/a through 1.1.8.

AnalysisAI

CVE-2025-52791 is a CSRF vulnerability in devfelixmoira Knowledge Base Maker (versions up to 1.1.8) that enables Stored XSS attacks, allowing unauthenticated remote attackers to inject malicious scripts that persist and execute in users' browsers. The vulnerability requires user interaction (clicking a malicious link) but can affect multiple users through stored payloads, with a CVSS score of 7.1 indicating medium-high severity. No KEV listing or confirmed EPSS data is available in public sources, and patch availability status requires verification with the vendor.

Technical ContextAI

This vulnerability combines two distinct attack vectors: CSRF (CWE-352) as the primary classification and Stored XSS as the secondary impact. CSRF exploits the trust between a user's browser and the Knowledge Base Maker application by tricking authenticated users into performing unintended actions without their knowledge. The vulnerability chain likely involves insufficient CSRF token validation or missing anti-CSRF protections on state-changing operations (such as creating, editing, or deleting knowledge base entries). The Stored XSS component indicates that user-supplied input is persisted in the database without proper sanitization or encoding, and later rendered to other users without escaping HTML/JavaScript context. The affected product is devfelixmoira Knowledge Base Maker (CPE pattern: cpe:2.3:a:devfelixmoira:knowledge_base_maker:*:*:*:*:*:*:*:*), specifically versions 1.1.8 and below. The attack vector is Network (AV:N) with Low complexity (AC:L) and no privilege requirements (PR:N), meaning any remote actor can craft a malicious CSRF request.

RemediationAI

Upgrade to Knowledge Base Maker version 1.1.9 or later when available from devfelixmoira.; priority: High Mitigation - Input Validation: Implement strict input validation and sanitization for all user-supplied data before storing in the database. Use a whitelist-based approach to allow only safe HTML tags if rich text is necessary.; priority: High Mitigation - Output Encoding: Apply context-aware output encoding when rendering knowledge base content. Use HTML entity encoding for HTML context and JavaScript encoding for script context.; priority: High Mitigation - CSRF Protection: Implement anti-CSRF tokens (e.g., synchronizer token pattern or double-submit cookies) on all state-changing endpoints. Verify token presence and validity on the server side.; priority: High Mitigation - CSP: Deploy Content Security Policy (CSP) headers to restrict script execution from unauthorized sources, limiting XSS impact even if injection occurs.; priority: Medium Workaround: Restrict write access to knowledge base content to trusted administrators only. Implement role-based access control (RBAC) to minimize exposure surface.; priority: Medium Vendor Advisory: Monitor devfelixmoira security advisories and GitHub repository for patch releases. Contact vendor directly if no patch timeline is provided.; priority: Medium
