CVE-2025-0741 is classified as an improper access control vulnerability found in thesamur's embedai version 2.1 and below. This vulnerability allows an authenticated attacker to write messages into other users' chats by manipulating the "chat_id" parameter in the POST request to "/embedai/chats/send_message". The severity of this vulnerability is rated as medium, with a CVSS score of 5.8, which indicates it poses a moderate risk to organizations.
The exploitation of this vulnerability could lead to unauthorized messages being sent in user chats, potentially resulting in misinformation or other malicious actions. The attack vector is through the network, requiring low complexity and no privileges or user interaction, making it easier for attackers to exploit.
Organizations utilizing embedai should prioritize patching as soon as possible to prevent potential exploitation. The urgency to address this vulnerability is high due to its nature and the impact it can have on user trust and data integrity.
Currently, there are no known exploits in the wild for this vulnerability, but organizations are encouraged to monitor for any updates or advisories regarding its status.
In summary, CVE-2025-0741 presents a medium risk to organizations using thesamur's embedai. Immediate action is recommended to mitigate potential threats associated with this vulnerability.
Vulnerability Details
The official description indicates that this improper access control vulnerability allows authenticated attackers to interact maliciously with other users' chat sessions. The CVSS score of 5.8, as determined by the cve-coordination@incibe.es organization, signifies a medium severity level. The affected product is embedai by thesamur, specifically versions 2.1 and below, with a publication date of January 30, 2025.
The vulnerability has been classified under CWE-284, denoting improper access control, which makes it crucial for developers to ensure strict validation of user permissions in chat functionalities.
Technical Analysis
The root cause of CVE-2025-0741 lies in inadequate access control mechanisms within the embedai application. Attackers can exploit this by crafting a request that alters the "chat_id" parameter, allowing them to communicate in chats not intended for them. This is particularly concerning as it does not require any special privileges, making it accessible to any authenticated user.
The attack vector is network-based, with low complexity, meaning that attackers can execute this exploit easily without sophisticated techniques. There is no need for user interaction, further lowering the barriers for exploitation.
In terms of impact, the confidentiality of chat data remains intact, while the integrity is compromised due to the possibility of sending unauthorized messages. The availability of the service remains unaffected.
Risk & Impact Analysis
Organizations utilizing the embedai platform face significant risks due to this vulnerability. The potential for attackers to manipulate chat interactions could lead to a loss of trust among users, misinformation, and possible data breaches if sensitive discussions are inadvertently exposed. The blast radius includes all users of the embedai service, highlighting the need for immediate remediation.
Considering the CVSS score and the lack of known exploits, organizations should assess their risk management strategies and prioritize patching as part of their security protocols. The urgency of addressing this vulnerability is categorized as high due to its potential implications on user interactions.
