Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions of the nostr crate before 0.44.7 are vulnerable. An empty NIP-50 search value in a filter can make event matching panic, so a remote client that can submit filters to an application using this matcher, including clients of an SDK local relay, can cause a denial of service. Depending on panic handling, this may stop one request, a runtime worker, or the whole process. Upgrade to nostr 0.44.7 or later.
