CVE-2025-49236 is a medium-severity vulnerability classified under CWE-862, which refers to Missing Authorization. This vulnerability affects the Raychat product up to version 2.1.0. The core issue is that certain functionalities within Raychat are accessible without proper access control lists (ACLs) enforcement, allowing unauthorized users to invoke functions that should be restricted. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N), the vulnerability can be exploited remotely over the network without any privileges or user interaction, making it relatively easy to exploit. The impact is limited to integrity loss, meaning unauthorized users can perform actions that modify data or system state in unintended ways, but confidentiality and availability are not directly affected. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on June 6, 2025, and was reserved just two days earlier, indicating it is a recently disclosed issue. Missing authorization vulnerabilities like this can lead to unauthorized changes in chat configurations, user roles, or message content, potentially undermining trust and operational security within affected organizations using Raychat for communication.

For European organizations using Raychat, this vulnerability poses a risk of unauthorized modification of chat system data or settings, which could disrupt internal communications or lead to misinformation. Since Raychat is a communication platform, unauthorized integrity changes could facilitate social engineering, manipulation of chat logs, or unauthorized escalation of privileges within the chat environment. This could impact compliance with data integrity and security regulations such as GDPR, especially if manipulated data leads to incorrect decision-making or exposure of sensitive workflows. The lack of required authentication and user interaction increases the risk of automated exploitation attempts, potentially affecting organizations that rely heavily on Raychat for customer or internal communications. However, the absence of confidentiality or availability impact limits the scope of damage to data integrity concerns.

Organizations should immediately assess their use of Raychat and identify if they are running versions up to 2.1.0. Given no official patches are currently linked, mitigation should include implementing network-level access controls to restrict access to Raychat services only to trusted users and IP ranges. Monitoring and logging access to Raychat functionalities can help detect unauthorized usage attempts. Employing Web Application Firewalls (WAFs) with custom rules to detect and block anomalous requests targeting Raychat APIs or functions may reduce exploitation risk. Organizations should also engage with the vendor for timely patch releases and apply updates as soon as they become available. Additionally, reviewing and tightening internal access policies and user permissions within Raychat can limit the potential damage from unauthorized function access. Conducting regular security audits and penetration testing focused on authorization controls in Raychat deployments is recommended to proactively identify and remediate similar issues.
