Threat metrics

Exploit Maturity: POC

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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: 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 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 14 Dec 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

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 all instances of Mayan EDMS to version 4.10.2 or later to remediate this vulnerability. For environments where immediate upgrade is not feasible, applying vendor-provided backported patches for older versions as soon as they become available is essential. Additionally, organizations should implement strict input validation and output encoding on all user-supplied data within the /authentication/ module to prevent script injection. Deploying Web Application Firewalls (WAFs) with rules targeting XSS attack patterns can provide temporary protection. User awareness training should emphasize caution with unsolicited links and emails to reduce the risk of successful social engineering. Monitoring web server logs for suspicious requests targeting the /authentication/ path can help detect attempted exploitation. Finally, organizations should review session management policies to ensure secure cookie attributes (HttpOnly, Secure, SameSite) are enforced to mitigate session hijacking risks.

Description

A vulnerability was detected in Mayan EDMS up to 4.10.1. The affected element is an unknown function of the file /authentication/. The manipulation results in cross site scripting. The attack may be performed from remote. The exploit is now public and may be used. Upgrading to version 4.10.2 is sufficient to fix this issue. You should upgrade the affected component. The vendor confirms that this is "[f]ixed in version 4.10.2". Furthermore, that "[b]ackports for older versions in process and will be out as soon as their respective CI pipelines complete."

Impact

For European organizations, the primary impact of CVE-2025-14691 lies in the potential compromise of user sessions and the integrity of document management workflows. Since Mayan EDMS is used to manage sensitive corporate and governmental documents, successful exploitation could enable attackers to execute malicious scripts that steal session cookies, perform unauthorized actions on behalf of users, or deliver phishing payloads. This could lead to unauthorized access to documents, manipulation of document metadata, or social engineering attacks targeting employees. While confidentiality and availability impacts are limited, the integrity and trustworthiness of document management systems are critical for compliance with European data protection regulations such as GDPR. Organizations relying on Mayan EDMS for regulated data processing or legal document management may face reputational damage and regulatory scrutiny if exploited. The lack of authentication requirement for exploitation increases the risk of widespread attacks, especially in environments where users are not trained to recognize phishing attempts or suspicious links.

Summary

CVE-2025-14691 is a Cross Site Scripting (XSS) vulnerability identified in Mayan EDMS, an open-source electronic document management system widely used for organizing and managing digital documents. The vulnerability affects versions 4.10.0 and 4.10.1 and resides in an unspecified function within the /authentication/ directory of the application. This flaw allows an attacker to inject malicious scripts that execute in the context of the victim's browser when they interact with crafted input, such as a specially crafted URL or form submission. The vulnerability is remotely exploitable without requiring any authentication, though it does require user interaction (e.g., clicking a malicious link). The impact primarily concerns the integrity of user sessions and potential execution of unauthorized scripts, which could lead to session hijacking, phishing, or defacement attacks. However, the vulnerability does not directly compromise confidentiality or availability. The vendor has addressed the issue in Mayan EDMS version 4.10.2 and is actively backporting fixes for older supported versions. No public exploits have been observed in the wild yet, but the exploit code is publicly available, increasing the risk of opportunistic attacks. The CVSS v4.0 base score is 5.3, reflecting a medium severity level due to the ease of exploitation and limited impact scope.
