Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Subsequent System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Fairsketch RISE CRM Framework to 3.9.

AI-suggested

1. 2. Input validation: Implement strict server-side validation and sanitization of all user inputs, especially the 'first_name' parameter, to neutralize HTML and script content before processing. 3. Output encoding: Ensure that any user-supplied data rendered in web pages is properly encoded to prevent script execution. 4. Web Application Firewall (WAF): Deploy and configure a WAF with rules to detect and block XSS payloads targeting the CRM endpoints. 5. Content Security Policy (CSP): Enforce a strong CSP to restrict the execution of unauthorized scripts in browsers. 6. User awareness: Train CRM users to recognize suspicious links or inputs that could trigger XSS attacks. 7. Logging and monitoring: Enable detailed logging of POST requests to '/clients/save_contact/' and monitor for anomalous input patterns indicative of injection attempts. 8. Segmentation: Limit access to the CRM system to trusted networks and users to reduce exposure. 9. Incident response: Prepare procedures to quickly respond to detected exploitation attempts, including session invalidation and forensic analysis.

Description

HTML injection vulnerability found in Fairsketch's RISE CRM Framework v3.8.1, which consist of an HTML code injection due to lack of proper validation of user inputs by sending a POST request in parameter 'first_name' in '/clients/save_contact/'.

Impact

For European organizations, the impact of CVE-2025-41106 can be significant, especially for those relying on Fairsketch RISE CRM Framework in customer management and communication workflows. Exploitation could enable attackers to execute malicious scripts in users' browsers, potentially leading to theft of session cookies, unauthorized access to sensitive customer data, or manipulation of CRM records through social engineering or phishing attacks. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data exposure), and operational disruptions. Sectors such as finance, healthcare, and retail, which handle sensitive personal data, are particularly vulnerable. The medium CVSS score reflects moderate risk, but the ease of exploitation without authentication and the widespread use of web browsers increase the threat surface. Additionally, the vulnerability could be leveraged as a foothold for more complex attacks or lateral movement within an organization's network. European organizations with public-facing CRM portals are at higher risk, especially if they have not implemented compensating controls like web application firewalls or strict content security policies.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
