Security readout for executives and security teams
Plain-English summary
A malicious Wire message could run attacker-controlled code when a recipient viewed it. In vulnerable self-hosted Wire web deployments, that could let the attacker act as the victim account. Wire says managed services were already updated; on-premise operators must update because no workaround is listed.
Executive priority
Treat this as urgent for any self-hosted Wire environment. The issue could compromise confidentiality, integrity, and availability of user accounts after message viewing. Managed Wire services are reported already updated, so priority depends on whether your organization runs on-premise Wire.
Technical view
CVE-2022-29168 is a critical stored XSS in wire-webapp @mention rendering caused by insufficient escaping. The advisory maps it to CWE-79/CWE-80 and scores it CVSS 9.6. Vulnerable wire-desktop clients are affected when connected to a vulnerable wire-webapp version.
Likely exposure
Exposure is most likely in on-premise Wire deployments running wire-webapp before 2022-05-04-production.0, the listed fixed Docker tag, or wire-server before 2022-05-04 chart/4.11.0. Wire managed services are reported fixed.
Exploitation context
The source describes attack by receiving and viewing a malicious message, with no authentication required but user interaction required. The bundle does not cite CISA KEV listing or public active exploitation evidence, so active exploitation is not established here.
Researcher notes
Key uncertainty is exploitation in the wild; the bundle provides severity and impact but no active exploitation evidence. Validation should focus on version provenance and deployment topology, especially desktop clients attached to self-hosted webapp instances.
Mitigation direction
- Update wire-webapp to 2022-05-04-production.0 or later.
- For on-premise Docker, use tag 2022-05-04-production.0-v0.29.7-0-a6f2ded or later.
- For wire-server, upgrade to 2022-05-04 chart/4.11.0 or later.
- Confirm desktop clients connect only to patched wire-webapp instances.
- Because no workaround is listed, prioritize vendor update guidance.
Validation and detection
- Inventory all Wire managed and on-premise webapp instances.
- Verify deployed wire-webapp versions, Docker tags, and wire-server chart versions.
- Confirm any wire-desktop users are not bound to vulnerable webapp versions.
- Use safe regression testing to confirm @mention HTML is escaped.
- Review account activity and message telemetry for suspicious behavior.

Conservative CVE-to-ATT&CK context
These mappings and lookup hints may be relevant to the vulnerability behavior, CWE, affected product, or exposure path. Glexia-inferred context is not an official MITRE, ATT&CK, CWE, or CVE Program mapping.
ATT&CK lookup starting points
Use these exact CWE pages and searches to review the Glexia ATT&CK library from this CVE's weakness and description context.
CWE-79: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCWE-80: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupExecution behavior lookup
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
