Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

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

Description

Cross-site scripting in certain Zoom Clients before version 6.4.5 may allow an authenticated user to conduct a disclosure of information via network access.

Impact

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.

Compound weaknessLikelihood of exploit: MediumCWE Top 25 (2025): #3OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
Architecture and Design
Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
