Machine-written summary

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

GHSA-p6gw-4frg-j7jw affects the wsgidav package before 4.3.5, specifically its sample MySQLBrowserProvider, which builds SQL by concatenating the record key from the request URL without escaping. An unauthenticated user who can reach a share backed by this provider can inject SQL and read arbitrary data from the database. The provider is only an example and is not enabled by default. Upgrade wsgidav to 4.3.5 or later.
