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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.
No public nuclei template indexed

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

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

Organizations should immediately verify the version of Zoom Workplace for macOS deployed and plan to upgrade to version 6.5.10 or later once available. If you cannot patch yet, restrict local access to macOS devices running Zoom Workplace to trusted users only, employing strict endpoint access controls and user account management. Implement application whitelisting and monitor for unusual file access patterns related to Zoom Workplace directories. Educate users about the risk of interacting with suspicious prompts or files within Zoom Workplace. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. Regularly audit local user permissions and remove unnecessary privileges to minimize the risk of exploitation. Additionally, maintain up-to-date backups and ensure that sensitive data is encrypted at rest to reduce the impact of potential information disclosure.

Description

External control of file name or path in Zoom Workplace for macOS before version 6.5.10 may allow an authenticated user to conduct a disclosure of information via local access.

Impact

For European organizations, this vulnerability poses a risk primarily to confidentiality, as sensitive information could be disclosed to unauthorized users with local access. Organizations with macOS endpoints running Zoom Workplace are at risk, especially in environments where multiple users share devices or where endpoint security is lax. The impact is heightened in sectors handling sensitive or regulated data, such as finance, healthcare, and government institutions. Since the vulnerability requires local authenticated access and user interaction, remote exploitation is unlikely, but insider threats or compromised endpoints could leverage this flaw. The lack of impact on integrity and availability reduces the risk of disruption but does not diminish the potential for data breaches. Given Zoom's widespread use across Europe, particularly in corporate and educational sectors, the vulnerability could affect a broad range of organizations if not mitigated promptly.

CWE-73External Control of File Name or Path (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product allows user input to control or influence paths or file names that are used in filesystem operations.
Architecture and Design
When the set of filenames is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames, and reject all other inputs. For example, ID 1 could map to "inbox.txt" and ID 2 could map to "profile.txt".
Architecture and Design · Operation
Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict all access to files within a particular directory.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
