MATTERMOST MARKUP PATCH

Refer to the вЂњUpcoming changes in GoвЂќ section for details. The Go security team has agreed to Mattermost coordinating disclosure prior to making their changes public in order to minimize impact to parts of the ecosystem that canвЂ™t benefit from the new API.Go is introducing publicly-visible API changes related to these issues in an upcoming major release, which risks making the vulnerabilities public without explicit public disclosure.

The Go security team has determined that the root causes of the vulnerabilities cannot be reliably addressed.

There are three reasons why we are doing this now: We donвЂ™t take this type of public disclosure lightly, and it has not been an easy decision to make. If you maintain a Go-based project that relies on XML integrity, we urge you to read this post carefully. The implications of these vulnerabilities in key use cases we have identified present a material security concern. Downstream projects that assume certain integrity guarantees from GoвЂ™s standard library are vulnerable when those guarantees do not hold. The mitigation for the remaining issues will be adding a new mode in Go to make explicit that these vulnerabilities exist. Only one of the three is on the roadmap to be patched in the foreseeable future (see вЂњUpdate вЂќ below).

See вЂњNo impact to Mattermost customersвЂќ below for more info.Дespite significant efforts by the Go security team, it has not been possible to patch the vulnerabilities discussed in this blog post. These issues do not impact Mattermost customers. The public disclosure comes as a result of several months of work, including collaborating with the Go security team since August 2020 and with affected downstream project maintainers since earlier this month.В There are several potential security problems created by these vulnerabilities, one of which is a complete bypass of SAML authentication.
