Hi, devs. While reviewing our attachment archive implementation I found following methods in com.xpn.xwiki.api.Attachment: /** * @return the rcs archive of the attachement */ public Archive getArchive() { return attachment.getArchive(); } It returns unwrapped JRCS archive which Has modify methods. So user can change attachment archive without proper rights. Also there are public archive-specific methods in api.Attachment such as getVersions, getAttachmentRevision. So I found no usecases of getArchive method. This method can be replaced by api.Attachment.getAttachment().getArchive() with checking programming right. next method: public XWikiAttachment getAttachmentRevision(String rev) throws XWikiException { return attachment.getAttachmentRevision(rev, getXWikiContext()); } returns unwrapped XWikiAttachment, but should return api.Attachment. So i propose to delete api.Attachment#getArchive() and modify getAttachmentRevision to return Attachment. Another question: is this fix needed for 1.3 brunch? Here is my +1 for fix it in trunk. -- Artem Melentyev
