Directory Traversal

matrix-js-sdk is a Matrix Client-Server SDK for Javascript

Affected versions of this package are vulnerable to Directory Traversal via crafted MXC URIs. An attacker can issue arbitrary authenticated GET requests to the client's homeserver by exploiting insufficient validation of the server-name and media-id components in MXC URIs.

How to fix Directory Traversal?

Upgrade matrix-js-sdk to version 34.11.1 or higher.

<34.11.1

Improper Authentication

matrix-js-sdk is a Matrix Client-Server SDK for Javascript

Affected versions of this package are vulnerable to Improper Authentication through the sendSharedHistoryKeys method. An attacker can intercept and obtain sensitive historical keys by injecting malicious devices into the communication without proper verification of the user's cryptographic identity. This is only exploitable if the client is running the legacy crypto stack.

Note:

This vulnerability does not affect users using the new Rust cryptography stack (i.e., those that call MatrixClient.initRustCrypto() instead of MatrixClient.initCrypto()).

How to fix Improper Authentication?

Upgrade matrix-js-sdk to version 34.8.0 or higher.

>=9.11.0 <34.8.0

Uncontrolled Recursion

matrix-js-sdk is a Matrix Client-Server SDK for Javascript

Affected versions of this package are vulnerable to Uncontrolled Recursion via the getRoomUpgradeHistory function. An attacker can cause the application to hang by crafting a room or room structure with cyclical predecessors.

How to fix Uncontrolled Recursion?

Upgrade matrix-js-sdk to version 34.3.1 or higher.

<34.3.1

Missing Authorization

matrix-js-sdk is a Matrix Client-Server SDK for Javascript

Affected versions of this package are vulnerable to Missing Authorization which can lead to invisible eavesdropping in group calls, on the video and audio of participants without their knowledge. The attacker will not appear to be participating in the call.

Notes: Legacy 1:1 calls are unaffected.

How to fix Missing Authorization?

Upgrade matrix-js-sdk to version 24.1.0 or higher.

<24.1.0

Prototype Pollution

matrix-js-sdk is a Matrix Client-Server SDK for Javascript

Affected versions of this package are vulnerable to Prototype Pollution such that events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely.

Note: The matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer.

How to fix Prototype Pollution?

Upgrade matrix-js-sdk to version 24.0.0 or higher.

<24.0.0
