Zoom Workplace for Android: Improper Neutralization of Special Elements in Output Used by a Downstream Component
CVE-2025-64741 is a critical-severity improper neutralization of special elements in output used by a downstream component vulnerability in Zoom Workplace for Android from Zoom Communications, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.5.10 as the first without the flaw, so updating Zoom Workplace for Android to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Zoom Workplace for Android to 6.5.10 or a later version.
- Update Meeting Software Development Kit to 6.5.10 or a later version.
- Update Workplace to 6.5.10 or a later version.
- Read the advisory on zoom.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Improper Neutralization of Special Elements in Output Used by a Downstream Component
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
How developers prevent this class of flaw
- Programming languages and supporting technologies might be chosen which are not subject to these issues.
- Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
