VoiceTra provided by National Institute of Information and Communications Technology (NICT) contains an incorrectly specified destination in a communication channel vulnerability. Users may be directed to a server (or service) controlled by an attacker, potentially resulting in the theft of input data or the display of incorrect results.
AnalysisAI
VoiceTra, a voice translation mobile application developed by Japan's National Institute of Information and Communications Technology (NICT), fails to correctly validate the destination server for its translation API communications (CWE-941), affecting both Android and iOS versions across all releases. An attacker capable of intercepting or redirecting the app's network traffic can substitute a malicious server, enabling theft of spoken or typed translation input and delivery of falsified translation output to the user. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must occupy a network position between the VoiceTra app and NICT's backend translation servers - achieved via rogue access point, ARP spoofing on a shared LAN, or DNS manipulation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.0 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N) yields a score of 5.4 (Medium), reflecting a meaningful but bounded real-world risk: impact is limited to translation data confidentiality and output integrity, and exploitation requires the user to actively initiate a translation request (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Users should update VoiceTra to the patched version as soon as NICT releases it; the vendor advisory at https://www.nict.go.jp/en/topics/2026/08/10-1.html should be monitored for the confirmed fix version, which is not independently confirmed in the current data. … Detailed patch versions, workarounds, and compensating controls in full report. |
