Security readout for executives and security teams
Plain-English summary
This is a medium-severity cross-site scripting issue in some Zoom Workplace Apps. It requires an attacker on an adjacent network and user interaction, so broad internet-wide compromise is not indicated by the supplied sources. Successful abuse could affect content integrity, with limited confidentiality and integrity impact and no stated availability impact.
Executive priority
Treat this as a moderate operational patching item, not an emergency based on supplied evidence. Prioritize confirmation of affected Zoom Workplace App versions, then apply vendor guidance through normal endpoint management, especially for sensitive users or shared networks.
Technical view
CVE-2025-27441 is CWE-79 cross-site scripting in some Zoom Workplace Apps. CVSS 3.1 is 4.6 with AV:A, AC:L, PR:N, UI:R, S:U, C:L, I:L, A:N. The supplied data does not list specific affected versions, patch levels, or detailed attack prerequisites beyond adjacent network access and required user interaction.
Likely exposure
Organizations using Zoom Workplace Apps may be exposed only if they run versions identified by Zoom's bulletin. The source bundle states default status is unaffected and refers version details to vendor references, so exposure cannot be confirmed from the CVE metadata alone.
Exploitation context
The source bundle does not state active exploitation, and the CVE is not listed as KEV. Exploitation is constrained by adjacent network access and user interaction, reducing likelihood compared with remotely exploitable, no-click issues. Evidence is insufficient to assess public proof-of-concept availability.
Researcher notes
Key missing details are affected versions, fixed versions, and exact vulnerable app context. Avoid assuming all Zoom clients are affected. The CVSS vector indicates adjacent-network, unauthenticated access with required user interaction and limited confidentiality and integrity impact.
Mitigation direction
- Review Zoom bulletin ZSB-25013 for affected app and version details.
- Update or remediate according to Zoom's published guidance.
- Inventory Zoom Workplace Apps across managed endpoints.
- Reduce adjacent-network exposure where feasible through standard network segmentation.
- Prioritize users or systems handling sensitive Zoom workflows.
Validation and detection
- Compare installed Zoom Workplace Apps against Zoom bulletin ZSB-25013.
- Confirm whether deployed versions match the affected range.
- Verify remediation status after applying Zoom guidance.
- Check vulnerability management tools for CVE-2025-27441 coverage.
- Review browser or endpoint alerts for suspicious script behavior.

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.
