CVE-2025-26371 is a high-severity vulnerability classified as a CWE-862 "Missing Authorization" issue. This vulnerability allows an authenticated (low-privileged) attacker to add users to groups via crafted HTTP requests in Q-Free MaxTime versions less than or equal to 2.11.0. With a CVSS base score of 8.8, this vulnerability poses a significant risk due to its potential impact on confidentiality, integrity, and availability.
Risk to organizations includes unauthorized access to sensitive group functionalities, enabling low-privileged users to escalate their privileges. The exploitation of this vulnerability can lead to severe ramifications, particularly in environments where access control is critical. Organizations using affected versions should take immediate action to remediate.
As of now, there is no confirmed public exploit available for this vulnerability, but the high CVSS score indicates a strong potential for exploitation. Organizations should prioritize patching immediately to protect against possible attacks leveraging this vulnerability.
The urgency for defenders is heightened given the vulnerability's classification and potential impact. It is advisable that organizations assess their current deployments of Q-Free MaxTime and take appropriate measures.
Vulnerability Details
The official description of CVE-2025-26371 states: "A CWE-862 'Missing Authorization' in maxprofile/user-groups/routes.lua in Q-Free MaxTime less than or equal to version 2.11.0 allows an authenticated (low-privileged) attacker to add users to groups via crafted HTTP requests." This vulnerability is classified under CWE-862, indicating issues related to authorization failures.
The CVSS score of 8.8 categorizes this vulnerability as high severity, highlighting the critical nature of the issue. Affected systems include Q-Free MaxTime versions up to 2.11.0. The vulnerability was published on February 12, 2025, and has been analyzed for its impact.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper authorization checks within the maxprofile/user-groups/routes.lua file. Attackers can exploit this by sending specially crafted HTTP requests to manipulate user group assignments without sufficient privileges.
The attack vector is network-based, requiring low complexity for exploitation. Only low privileges are required, and user interaction is not necessary for this vulnerability to be exploited. The potential impact is severe, as it can affect confidentiality, integrity, and availability, which makes this vulnerability particularly dangerous.
Risk & Impact Analysis
Organizations utilizing Q-Free MaxTime need to be aware of the real-world risks associated with this vulnerability. If successfully exploited, it can lead to unauthorized access to sensitive functionalities, compromising user data and overall system integrity.
The blast radius for this vulnerability could be significant, considering the application’s use in critical infrastructure and services that require stringent access controls. Organizations must assess their exposure to this vulnerability and implement urgent measures to mitigate risk.
The urgency for remediation is high, given the high CVSS score and potential exploitation. Organizations should prioritize this vulnerability in their patch cycle, ensuring that they remain vigilant against potential threats.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
