Exploitation Conditions

Exploitation requires the attacker to have physical access to the iOS device (AV:P as confirmed by CVSS vector) and to be an authenticated user with high privileges on the Zoom application (PR:H). The vulnerable device must be running Zoom Workplace for iOS on any version below 7.0.0. Remote exploitation is not possible - the physical access vector is a hard constraint. The high privilege requirement further limits the attack to users who already have significant authorization within the Zoom application context. The limited confidentiality impact (C:L) means only a subset of information is at risk, not full data exposure. Non-iOS platforms are not implicated in the available data.

Impact

Real-world risk is very low across all available signals. The CVSS score of 1.8 reflects three compounding constraints: physical access required (AV:P), high privileges required (PR:H), and only low confidentiality impact (C:L) with no integrity or availability impact. EPSS is 0.02% at the 5th percentile, meaning fewer than 5% of CVEs are less likely to be exploited - this is one of the least likely exploitation scenarios statistically. SSVC signals are similarly benign: exploitation status is none, the attack is not automatable, and technical impact is only partial. No KEV listing and no public exploit code have been identified. The combination of needing to be physically present, already authenticated (PR:H), and on an unpatched iOS device makes opportunistic or remote exploitation impossible. This is a low-priority vulnerability for most organizations, with patch application being sufficient and urgent remediation unlikely to be necessary.

Exploit ScenarioDerived

An individual with physical access to an unlocked iOS device - for example, an IT administrator or someone who finds an unattended device - opens or interacts with the Zoom Workplace app on a version prior to 7.0.0 and is able to view information that should be protected by an iOS security mechanism, such as cached screen content, notification details, or data surfaced through an accessibility interface. No exploit code or POC has been identified at time of analysis. The physical access and high privilege prerequisites make this scenario realistically confined to insider threat or device theft contexts.

AnalysisAIv1 – Jun 08, 2026

Information disclosure in Zoom Workplace for iOS before version 7.0.0 allows an authenticated user with physical access to the device to read limited confidential data by exploiting a failed protection mechanism. The vulnerability is constrained by both physical proximity and high privilege requirements, yielding a CVSS score of 1.8 - among the lowest possible. No active exploitation has been identified, and Zoom has released a fix in version 7.0.0 per their security bulletin ZSB-26006.

RemediationAI

Upgrade Zoom Workplace for iOS to version 7.0.0 or later, as confirmed by Zoom's security bulletin ZSB-26006 (https://www.zoom.com/en/trust/security-bulletin/zsb-26006). Updates can be applied via the Apple App Store. For environments where an immediate upgrade is not possible, restrict physical access to devices running the Zoom Workplace app - this directly addresses the AV:P prerequisite and eliminates the attack surface entirely. Additionally, enabling iOS device management controls such as MDM-enforced screen lock, disabling app background snapshots through MDM profiles, and restricting lock screen notification content for the Zoom app can serve as interim compensating controls. These measures have the trade-off of reducing usability but directly target the physical access vector.

Technical ContextAI · show details

The root cause is classified as CWE-693 (Protection Mechanism Failure), meaning a security control intended to guard access to sensitive information is either bypassed or non-functional under specific conditions. The affected product is the Zoom Workplace application on Apple iOS, identified by CPE cpe:2.3:a:zoom_communications:zoom_workplace:*:*:*:*:*:*:*:*. On iOS, protection mechanisms that can fail include screen-sharing restrictions, data-at-rest protections, background snapshot caching (iOS multitasking thumbnails), notification content exposure on the lock screen, clipboard access, or improper handling of iOS accessibility or screen recording APIs. The 'Apple' and 'Information Disclosure' tags corroborate that the issue is iOS-platform-specific and limited to confidentiality impact.

Attack Technique

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
