CVE-2025-41101 Overview
CVE-2025-41101 is an HTML injection vulnerability affecting Fairsketch RISE Ultimate Project Manager (RISE CRM Framework) version 3.8.1. The flaw stems from insufficient validation of user-supplied input in the title parameter of the /projects/save endpoint. An authenticated attacker can submit a crafted POST request that embeds arbitrary HTML markup into stored project data. When other users view the affected project, the injected content renders in their browsers. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation.
Critical Impact
Authenticated attackers can inject arbitrary HTML into stored project records, enabling phishing content delivery, UI redressing, and social engineering attacks against other CRM users.
Affected Products
- Fairsketch RISE Ultimate Project Manager (RISE CRM Framework) v3.8.1
- Deployments exposing the /projects/save endpoint to authenticated users
- Installations without a Web Application Firewall (WAF) filtering HTML metacharacters on project inputs

Technical Details for CVE-2025-41101
Vulnerability Analysis
The vulnerability resides in the project creation and update workflow of RISE CRM. The application accepts a title parameter through a POST request to /projects/save without sanitizing or encoding HTML metacharacters. The unvalidated value is persisted in the backend datastore and later rendered in project listings and detail views.
Because the payload is stored server-side, every user with visibility into the affected project processes the injected markup on load. The attack requires authentication and some user interaction to trigger, which limits reach compared to unauthenticated stored Cross-Site Scripting (XSS). However, RISE CRM is typically deployed for team collaboration, so injected content reaches project managers, staff, and clients invited to the workspace.
Successful exploitation supports phishing lures, fake login prompts, and content spoofing inside a trusted CRM interface. The advisory scope is limited to HTML injection rather than full script execution, though [CWE-79] often permits escalation depending on the surrounding template context.
Root Cause
The root cause is missing output encoding and input validation on the title field handled by the /projects/save controller. The framework treats user-supplied text as safe when rendering project metadata, violating the principle of contextual output escaping for HTML sinks.
Attack Vector
An authenticated user issues a POST request to /projects/save containing HTML tags such as anchor, image, or iframe elements inside the title parameter. The server stores the payload and serves it back to every user who loads the project view. See the INCIBE Security Notice on Fairsketch CRM Vulnerabilities for advisory details.
Detection Methods for CVE-2025-41101
Indicators of Compromise
- POST requests to /projects/save containing HTML tags such as <a>, <img>, <iframe>, or <form> in the title parameter
- Project titles in the database that contain angle brackets, embedded URLs, or encoded HTML entities
- User reports of unexpected links, images, or login prompts appearing inside project views
Detection Strategies
- Inspect HTTP request bodies to /projects/save for HTML metacharacters and known injection payloads in the title field
- Query the project database table for existing entries containing <, >, href=, or src= sequences in title columns
- Correlate authenticated session activity with anomalous project creation or update volume from a single account
Monitoring Recommendations
- Enable web server access logging with full POST body capture on the /projects/save route
- Forward CRM application logs to a centralized Security Information and Event Management (SIEM) platform for pattern matching
- Alert on outbound requests from user browsers to unexpected domains referenced from CRM project pages
How to Mitigate CVE-2025-41101
Immediate Actions Required
- Restrict access to the RISE CRM instance to trusted network segments and authenticated users only
- Audit existing project titles for injected HTML content and remove or sanitize affected records
- Review recent account activity for unauthorized project creation or modification events
- Deploy a Web Application Firewall (WAF) rule that blocks HTML tags in project title parameters
Patch Information
At the time of publication, no vendor patch is referenced in the NVD entry or the INCIBE advisory for version 3.8.1. Administrators should monitor the INCIBE Security Notice on Fairsketch CRM Vulnerabilities and Fairsketch release channels for an official fix, and upgrade as soon as one becomes available.
Workarounds
- Apply server-side input validation that rejects HTML metacharacters in the title field before persisting project data
- Enforce contextual output encoding on all project fields rendered in HTML templates
- Configure a strict Content Security Policy (CSP) that disallows inline scripts and restricts loadable domains
- Limit project creation and editing privileges to a minimal set of trusted user roles
