Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Resty (cn.dreampie:resty) up to and including 1.3.1.SNAPSHOT has a path traversal flaw in the HttpClient Request function, where manipulation of the filename argument allows directory traversal. A remote attacker could exploit this, though the source describes the attack as highly complex and difficult, and a public exploit has been disclosed. The source gives no fixed version and the vendor did not respond to disclosure, so no fix is listed.
