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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 9 Sep 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

Given the absence of an official patch or update at this time, European organizations should implement several practical mitigations: 1) Limit the use of Zoom Workplace Clients for Windows to trusted users and environments, reducing exposure. 2) Educate users about the risk of social engineering and phishing attacks that could trigger the required user interaction for exploitation. 3) Employ network segmentation and monitoring to detect unusual network activity related to Zoom client communications. 4) Use endpoint protection solutions capable of detecting anomalous behavior in Zoom client processes. 5) Consider temporarily restricting or disabling Zoom Workplace Client usage on Windows systems in high-risk environments until a patch is available. 6) Maintain up-to-date inventories of affected software versions and monitor vendor advisories for patches or updates. 7) Enforce strict access controls and data encryption to minimize the impact of any potential information disclosure. 8) Implement multi-factor authentication and strong user authentication policies to reduce the risk of unauthorized access through other vectors, complementing the defense against this vulnerability.

Description

Improper action enforcement in certain Zoom Workplace Clients for Windows may allow an unauthenticated user to conduct a disclosure of information via network access.

Impact

For European organizations, this vulnerability poses a risk of unauthorized information disclosure through the Zoom Workplace client on Windows systems. Given the widespread use of Zoom products in corporate environments across Europe for remote work, meetings, and collaboration, sensitive corporate data, internal communications, or proprietary information could be exposed if exploited. The requirement for user interaction and high attack complexity somewhat limits the ease of exploitation; however, targeted phishing or social engineering campaigns could facilitate exploitation. The confidentiality impact is high, which could lead to data breaches, loss of competitive advantage, or regulatory non-compliance under GDPR if personal or sensitive data is leaked. Since the vulnerability does not affect integrity or availability, operational disruption is less likely, but the reputational and compliance consequences could be significant. Organizations relying heavily on Zoom Workplace for internal communications should consider this vulnerability seriously, especially those in regulated industries or handling sensitive information.

CWE-837Improper Enforcement of a Single, Unique Action (opens in a new tab)
Base weakness
The product requires that an actor should only be able to perform an action once, or to have only one unique action, but the product does not enforce or improperly enforces this restriction.
OWASP ASVS 4.0.3
V11.1.2 (opens in a new tab)
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
