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: Active: Successful exploitation of this vulnerability requires a targeted user to perform specific, conscious interactions with the vulnerable system and the attacker’s payload, or the user’s interactions would actively subvert protection mechanisms which would lead to exploitation of the vulnerability.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable 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.

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 2026-10-25.

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.

AI-suggested

European organizations should immediately upgrade Windu CMS installations to version 4.1 build 2250 or later, where the vulnerability is patched. Until the upgrade is applied, administrators should consider temporarily disabling open registration or restricting user editing capabilities to trusted roles only. Implement additional server-side validation to verify user actions beyond relying solely on CSRF tokens. Monitor user account activities for unusual modifications and implement anomaly detection to identify potential exploitation attempts. Educate users about phishing and social engineering risks to reduce the likelihood of successful CSRF attacks requiring user interaction. Review session management policies to ensure tokens are unique per user and cannot be reused across sessions. Conduct regular security audits and penetration testing focused on CSRF and related web vulnerabilities to proactively identify weaknesses.

Description

Windu CMS is vulnerable to Cross-Site Request Forgery in user editing functionality. Implemented CSRF protection mechanism can be bypassed by using CSRF token of other user. It is worth noting that the registration is open and anyone can create an account. Only version 4.1 was tested and confirmed as vulnerable. This issue was fixed in version 4.1 build 2250.

Impact

For European organizations using Windu CMS 4.1, this vulnerability could lead to unauthorized changes to user accounts, potentially allowing attackers to escalate privileges, alter user data, or disrupt normal user management workflows. This undermines the integrity of the CMS user base and could facilitate further attacks such as privilege escalation or social engineering. Organizations relying on Windu CMS for public-facing websites or internal portals may face reputational damage and operational disruption if exploited. The open registration feature increases the attack surface, as attackers can freely create accounts to exploit the vulnerability. While confidentiality and availability impacts are limited, the integrity compromise can have cascading effects on trust and security posture. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially given the medium CVSS score and ease of exploitation.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
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
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
