Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The github.com/go-jose/go-jose/v4 package before 4.1.5 and github.com/go-jose/go-jose/v3 at or below 3.0.5 are affected. Parsing deeply nested JSON from untrusted input can exhaust the stack and crash the application. Upgrade v4 to 4.1.5; no fixed v3 version is listed, so reject large inputs before parsing.
