CVE-2022-24799: wire-webapp is the web application interface for the wire messaging service.

wire-webapp is the web application interface for the wire messaging service.

wire-webapp is the web application interface for the wire messaging service. Insufficient escaping in markdown “code highlighting” in the wire-webapp resulted in the possibility of injecting and executing arbitrary HTML code and thus also JavaScript. If a user receives and views such a malicious message, arbitrary code is injected and executed in the context of the victim. This allows the attacker to fully control the user account. Wire-desktop clients that are connected to a vulnerable wire-webapp version are also vulnerable to this attack. The issue has been fixed in wire-webapp 2022-03-30-production.0 and is already deployed on all Wire managed services. On-premise instances of wire-webapp need to be updated to docker tag 2022-03-30-production.0-v0.29.2-0-d144552 or wire-server 2022-03-30 (chart/4.8.0), so that their applications are no longer affected. There are no known workarounds for this issue. ### Patches * The issue has been fixed in wire-webapp **2022-03-30-production.0** and is already deployed on all Wire managed services. * On-premise instances of wire-webapp need to be updated to docker tag **2022-03-30-production.0-v0.29.2-0-d144552** or wire-server **2022-03-30 (ch

What it means for a small business

If your business uses wire-webapp, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 1.00%, higher than 62% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 29, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
