In Wire for iOS (iPhone and iPad) before version 3.75 there is a vulnerability where the video capture isn't stopped in a scenario where a user first has their camera enabled and then disables it. It's a privacy issue because video is streamed to the call when the user believes it is disabled. It impacts all users in video calls. This is fixed in version 3.75.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-200"],"references":["https://github.com/wireapp/wire-ios/commit/7e3c30120066c9b10e50cc0d20012d0849c33a40","https://github.com/wireapp/wire-ios/pull/4879","https://github.com/wireapp/wire-ios/security/advisories/GHSA-7fg4-x8vj-qvxf","https://github.com/wireapp/wire-ios/commit/7e3c30120066c9b10e50cc0d20012d0849c33a40","https://github.com/wireapp/wire-ios/pull/4879"],"products":["wire:wire"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2021-21301","score":0.0102,"percentile":0.63413,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
