Security readout for executives and security teams
Plain-English summary
This is a medium-severity cross-site scripting issue in some Zoom Workplace Apps. An attacker on an adjacent network could potentially affect integrity, but the source data says user interaction is required and does not identify active exploitation. Exposure depends on the specific app versions listed by Zoom.
Executive priority
Treat this as a routine but real remediation item. It is not currently sourced as actively exploited, but affected Zoom app deployments should be identified and updated through normal endpoint management cycles.
Technical view
CVE-2025-27442 is CWE-79 cross-site scripting affecting some Zoom Workplace Apps. CVSS 3.1 is 4.6: adjacent network, low complexity, no privileges, user interaction required, unchanged scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Organizations using Zoom Workplace Apps versions identified in Zoom bulletin ZSB-25013 may be exposed. The provided CVE data does not list exact affected versions, so product inventory must be checked against Zoom's advisory.
Exploitation context
The CVE is not in KEV, and the provided sources do not state active exploitation. The CVSS vector limits likely attack context to adjacent network access with user interaction, reducing broad internet exposure.
Researcher notes
Key constraints are AV:A and UI:R, with limited C/I impact and no availability impact. Public details are sparse in the supplied bundle; avoid assuming exact affected versions, payload behavior, or exploitability beyond Zoom's bulletin and CVE metadata.
Mitigation direction
- Review Zoom security bulletin ZSB-25013 for affected versions and vendor guidance.
- Update affected Zoom Workplace Apps if Zoom provides fixed versions for your deployment.
- Prioritize systems used on shared, guest, or otherwise untrusted local networks.
- Track Zoom advisories until affected version details are fully confirmed internally.
Validation and detection
- Inventory deployed Zoom Workplace Apps and record exact versions.
- Compare installed versions with Zoom bulletin ZSB-25013.
- Confirm vulnerability tooling maps CVE-2025-27442 to the relevant Zoom assets.
- Document whether adjacent-network exposure is plausible for affected user devices.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
