CVE-2023-28427

matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 24.0.0 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 that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This vulnerability is distinct from GHSA-rfv9-x7hh-xc32 which covers a similar issue. The issue has been patched in matrix-js-sdk 24.0.0 and users are advised to upgrade. There are no known workarounds for this vulnerability.

Impact

In certain configurations, data sent by remote servers containing special strings in key locations could cause modifications of the Object.prototype, disrupting matrix-js-sdk functionality, causing denial of service and potentially affecting program logic.

(This is part 2, where CVE-2022-36059 / GHSA-rfv9-x7hh-xc32 is part 1. Part 2 covers remaining vectors not covered by part 1, found in a codebase audit scheduled after part 1.)

Patches

The issue has been patched in matrix-js-sdk 24.0.0.

Workarounds

None.
