OMERO.web provides a web based client and plugin infrastructure. Prior to version 5.29.2, if an error occurred when resetting a user's password using the Forgot Password option in OMERO.web, the error message displayed on the Web page can disclose information about the user. This issue has been patched in version 5.29.2. A workaround involves disabling the Forgot password option in OMERO.web using the omero.web.show_forgot_password configuration property.
