Submit #892779: SeaCMS 13.6 Cross Site Scriptinginfo

TitleSeaCMS 13.6 Cross Site Scripting
DescriptionSeaCMS 13.6 member profile update trusts the client-controlled oldpic hidden field. When no new avatar is uploaded, oldpic is stored in sea_member.pic and later rendered into img src attributes in member/admin pages and comment avatar output. A low-privileged member can store an attribute-breaking payload and trigger stored XSS.
