Attack Vector: Local
Attack Complexity: Low
Privileges Required: Low
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: High
Availability: None

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: 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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

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.

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 2026-10-26.

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 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.

What to do

AI-suggested

Organizations should immediately verify their Zoom Workplace VDI Plugin macOS Universal installer versions and plan to upgrade to versions 6.3.14, 6.4.14, or 6.5.10 or later once patches are released. Until patches are available, restrict access to the installer and limit installation privileges to trusted administrators only. Implement strict file system permissions and monitoring to detect unauthorized symlink creation or manipulation. Employ network segmentation to limit exposure of sensitive installation files and use endpoint security solutions capable of detecting suspicious file system activities. Educate users about the risks of interacting with untrusted files or installers and enforce multi-factor authentication to reduce the risk of unauthorized access. Regularly audit and review installation logs and network traffic for anomalies that may indicate exploitation attempts. Coordinate with Zoom support and subscribe to official advisories to receive timely updates on patches and mitigation guidance.

Description

Symlink following in the installer for the Zoom Workplace VDI Plugin macOS Universal installer before version 6.3.14, 6.4.14, and 6.5.10 in their respective tracks may allow an authenticated user to conduct a disclosure of information via network access.

Impact

The vulnerability poses a significant risk to organizations using the affected Zoom Workplace VDI Plugin on macOS systems. Exploitation could lead to unauthorized disclosure of sensitive information, including installation configuration files or credentials, which can undermine the confidentiality and integrity of the affected systems. This may facilitate further attacks such as privilege escalation, lateral movement, or targeted espionage within corporate networks. Since the vulnerability requires authentication and user interaction, the attack surface is somewhat limited; however, in environments with many users and frequent plugin installations or updates, the risk increases. The lack of availability impact means systems remain operational, but the breach of confidentiality and integrity can cause reputational damage, regulatory compliance issues, and financial losses. Organizations relying on Zoom for virtual desktop infrastructure should consider this vulnerability a priority for remediation to maintain secure communication and collaboration environments.
