CVE-2025-49462 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Zoom Communications Inc.'s Zoom Clients prior to version 6.4.5. The vulnerability is classified under CWE-352, which pertains to CSRF attacks. Specifically, this vulnerability allows an authenticated user to potentially disclose information via network access due to improper validation of requests within the Zoom client application. The vulnerability requires that the attacker have some level of authenticated access to the Zoom client, and user interaction is necessary to trigger the exploit. The CVSS v3.1 base score is 3.5, indicating a low severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N. This means the attack can be executed remotely over the network with low attack complexity, requires privileges (authenticated user), and user interaction. The impact is limited to confidentiality (partial information disclosure), with no impact on integrity or availability. There are no known exploits in the wild at the time of publication, and no patch links have been provided yet. The vulnerability was reserved in early June 2025 and published in July 2025. The affected versions are prior to 6.4.5, but the provided data lists affectedVersions as "0", which likely indicates all versions before 6.4.5 are vulnerable. This vulnerability is significant because Zoom is widely used for communication, and any information disclosure could lead to further targeted attacks or privacy violations.

For European organizations, the impact of CVE-2025-49462 is primarily related to confidentiality breaches within the Zoom client environment. Since Zoom is extensively used across various sectors including government, healthcare, finance, and education in Europe, even a low-severity information disclosure vulnerability can have serious implications. Sensitive meeting information, user credentials, or internal communication details could be exposed if exploited. This could lead to privacy violations under GDPR regulations, resulting in legal and financial repercussions. Moreover, information disclosed through this vulnerability could be leveraged by attackers to conduct more sophisticated attacks such as phishing or social engineering campaigns targeting European entities. However, the requirement for authenticated access and user interaction limits the scope of exploitation, reducing the likelihood of widespread impact. The absence of known exploits in the wild further reduces immediate risk but does not eliminate the potential for future exploitation.

1. Immediate upgrade to Zoom Client version 6.4.5 or later once available, as this version addresses the vulnerability. 2. Until patching is possible, restrict Zoom client usage to trusted networks and users to minimize exposure. 3. Implement strict access controls and multi-factor authentication (MFA) for Zoom accounts to reduce the risk of unauthorized authenticated access. 4. Educate users about the risks of interacting with unsolicited or suspicious links or requests within Zoom to prevent triggering CSRF attacks. 5. Monitor network traffic and Zoom client logs for unusual activity that may indicate exploitation attempts. 6. Coordinate with IT and security teams to enforce endpoint security policies that limit the execution of unauthorized scripts or commands within the Zoom client environment. 7. Engage with Zoom support or security advisories regularly to obtain patches or updates promptly. 8. Consider network segmentation and application whitelisting to limit the potential impact of any information disclosure.
