Authenticated file disclosure via post-filter space stripping
Published Nov 3, 2025 · Updated Nov 3, 2025
Path traversal in JEECG Jeewx-Boot allows remote authenticated users to read arbitrary server files through the imgurl parameter. WxActGoldeneggsPrizesController.getImgUrl passes the value to FileInputStream after getFileName removes traversal tokens before stripping spaces, so encoded spaces recreate dot segments after validation. A valid JSESSIONID is required; successful requests disclose files readable by the server process without modifying them.
