Serious vulnerabilities in Matrix’s end-to-end encryption have been patched

Developers of the open supply Matrix messenger protocol launched an replace on Wednesday to repair crucial end-to-end encryption vulnerabilities that subvert the confidentiality and authentication ensures that have been key to the platform’s meteoric rise.

Matrix is a sprawling ecosystem of open supply and proprietary chat and collaboration shoppers and servers which can be totally interoperable. The best-known app in this household is Element, a chat shopper for Windows, macOS, iOS, and Android, however there is a dizzying array of different members as nicely.


Matrix roughly goals to do for real-time communication what the SMTP normal does for e mail, which is to supply a federated protocol permitting consumer shoppers related to totally different servers to alternate messages with one another. Unlike SMTP, nevertheless, Matrix affords strong end-to-end encryption, or E2EE, designed to make sure that messages cannot be spoofed and that solely the senders and receivers of messages can learn the contents.

Matthew Hodgson—the co-founder and venture lead for Matrix and the CEO and CTO at Element, the maker of the flagship Element app—mentioned in an e mail that conservative estimates are that there are about 69 million Matrix accounts unfold all through some 100,000 servers. The firm at the moment sees about 2.5 million month-to-month lively customers utilizing its server, although he mentioned that is additionally probably an underestimate. Among the lots of of organizations asserting plans to construct inner messaging techniques primarily based on Matrix are Mozilla, KDE, and the governments of France and Germany.


On Wednesday, a workforce of researchers revealed analysis that reviews a number of vulnerabilities that undermine Matrix’s authentication and confidentiality ensures. All of the assaults described by the researchers require assistance from a malicious or compromised homeserver that targets the customers who hook up with it. In some instances, there are methods for skilled customers to detect an assault is underway.

The researchers privately reported the vulnerabilities to Matrix earlier this yr and agreed to a coordinated disclosure timed to Wednesday’s launch by Matrix of updates that handle probably the most critical flaws.

“Our attacks allow a malicious server operator or someone who gains control of a Matrix server to read the messages of users and to impersonate them to each other,” the researchers wrote in an e mail. “Matrix aims to protect against such behavior by providing end-to-end encryption, but our attacks highlight flaws in its protocol design and its flagship client implementation Element.”

Hodgson mentioned he disagrees with the researchers’ rivalry that a few of the vulnerabilities reside in the Matrix protocol itself and asserts they’re all implementation bugs in the primary era of Matrix apps, which embrace Element. He mentioned {that a} newer era of Matrix apps, together with ElementX, Hydrogen, and Third Room, are unaffected. There are not any indications that the vulnerabilities have ever been actively exploited, he added.
