Summary
Improper beacon events in matrix-js-sdk can result in availability issues
Details

Impact

Improperly formed beacon events (from MSC3488) can 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.

Patches

This is patched in matrix-js-sdk v19.7.0

Workarounds

Redacting applicable events, waiting for the sync processor to store data, and restarting the client can often fix it. Alternatively, redacting the applicable events and clearing all storage will fix the further perceived issues.

Downgrading to an unaffected version, noting that such a version may be subject to other vulnerabilities, will additionally resolve the issue.

References

N/A - This was a logic error in the SDK.
