### Impact The Matrix Federation API allows remote homeservers to request the *authorisation events* of events in a room. This is necessary so that a homeserver receiving some events can validate that those events are legitimate and permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver answering a query for authorisation events does not sufficiently check that the requesting server should be able to access them. Authorisation events include power level events (the list of user IDs and their power levels at the time) and relevant membership events (including the display name of the sender of that event), as well as events like `m.room.create`, `m.room.third_party_invite` and `m.room.join_rules`. Non-authorisation events are unaffected, so it isn't possible to e.g. extract message contents this way. This issue is only exploitable when a malicious actor knows the ID of a target room and the ID of an event from that room. In most cases...

### Impact bignum releases from v0.12.2 to v0.13.0 (inclusive) used node-pre-gyp to optionally download pre-built binary versions of the addon. These binaries were published on a now-expired S3 bucket which has since been claimed by a malicious third party which is now serving binaries containing malware that exfiltrates data from the user's computer. ### Patches v0.13.1 does not use node-pre-gyp and does not have support for downloading pre-built binaries in any form, avoiding the risk of malicious downloads.
