Security readout for executives and security teams
Plain-English summary
CVE-2022-31009 can make affected Wire for iOS clients crash repeatedly at launch after receiving invalid accent color data from another Wire user. The impact is availability only: users may be unable to use the iOS app until they upgrade or switch clients.
Executive priority
Moderate priority. This is not a confidentiality or integrity issue, but it can disrupt secure messaging for affected iOS users. Upgrade promptly where Wire supports business operations.
Technical view
wire-ios before 3.100 mishandled invalid accent color values. An unnecessary assert during integer-to-enum conversion raised an exception instead of falling back to a default, causing repeated client crashes. The vendor fixed this in Wire for iOS 3.100 and the referenced wire-ios commit.
Likely exposure
Exposure is limited to Wire for iOS users running versions earlier than 3.100. The source bundle does not identify other Wire clients, servers, or platforms as affected.
Exploitation context
The advisory says invalid accent colors can be used by and sent between Wire users. CVSS indicates network access, low complexity, low privileges, and user interaction. The provided sources do not show active exploitation, and KEV status is false.
Researcher notes
The issue maps to CWE-617: reachable assertion. The sources describe a crash from invalid enum conversion and a fixed fallback behavior. Evidence is sufficient for affected version and fix, but not for exploitation in the wild.
Mitigation direction
- Upgrade Wire for iOS to version 3.100 or later.
- Use another Wire client, such as the web app, until iOS clients are upgraded.
- Check Wire vendor guidance for any newer remediation details.
- Prioritize managed-device app updates for users who rely on Wire for operations.
Validation and detection
- Inventory Wire for iOS versions across managed and user-owned devices.
- Confirm affected devices are no longer running versions earlier than 3.100.
- Review mobile crash telemetry for repeated Wire iOS launch crashes.
- Verify no remediation assumptions are applied to unsupported platforms.
