Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Fesod (Incubating) fesod-sheet versions before 2.0.2-incubating are vulnerable to Server-Side Request Forgery through the UrlImageConverter component. An attacker who can supply an image URL can cause the server to make outbound requests to internal or otherwise restricted resources. Upgrade to fesod-sheet 2.0.2-incubating, which fixes this issue.
