Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Framework's spring-web module is affected in versions 7.0.0 through 7.0.7 and 6.2.0 through 6.2.18, due to incorrect host parsing in UriComponentsBuilder. Applications that use UriComponentsBuilder to parse and validate an externally supplied URL may be open to server-side request forgery, which an attacker could use to make the server send requests to unintended hosts. Upgrade spring-web to 7.0.8 or 6.2.19. The source gives few details about the exact attack conditions.
