SCA: security update for matrix-js-sdk (GHSA-6263-x97c-c4gg)

high Tenable Self-Hosted Container Security Plugin ID 411104

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Prior to version 19.7.0, an attacker
 cooperating with a malicious homeserver can construct messages appearing to have come from another person.
 Such messages will be marked with a grey shield on some platforms, but this may be missing in others. This
 attack is possible due to the matrix-js-sdk implementing a too permissive key forwarding strategy on the
 receiving end. Starting with version 19.7.0, the default policy for accepting key forwards has been made
 more strict in the matrix-js-sdk. matrix-js-sdk will now only accept forwarded keys in response to
 previously issued requests and only from own, verified devices. The SDK now sets a `trusted` flag on the
 decrypted message upon decryption, based on whether the key used to decrypt the message was received from
 a trusted source. Clients need to ensure that messages decrypted with a key with `trusted = false` are
 decorated appropriately, for example, by showing a warning for such messages. This attack requires
 coordination between a malicious homeserver and an attacker, and those who trust your homeservers do not
 need a workaround. (CVE-2022-39249)
