The MOD has been updated for this. I wasn't thinking and didn't re-sanitize the data from the recordset before inserting it into the POST_HISTORY table. There won't be any security issues, but obviously there is a problem. Replace the two INSERT statements with the ones below. Changes from 0.5b are marked in red.
strSql = "INSERT INTO " & strTablePrefix & "POST_HISTORY "
strSql = strSql & "(T_ID, T_SUBJECT, P_MESSAGE, P_AUTHOR, P_LAST_EDITBY, P_DATE) VALUES "
strSql = strSql & "(" & phTopicID & ", '" & ChkString(phTSubject,"sqlstring") & "', '" & ChkString(phTMessage,"sqlstring") & "', " & phTAuthor & ", " & phTLastEditby & ", '" & phTDate & "')"
strSql = "INSERT INTO " & strTablePrefix & "POST_HISTORY "
strSql = strSql & "(R_ID, P_MESSAGE, P_AUTHOR, P_LAST_EDITBY, P_DATE) VALUES "
strSql = strSql & "(" & phReplyID & ", '" & ChkString(phRMessage,"sqlstring") & "', " & phRAuthor & ", " & phRLastEditby & ", '" & phRDate & "')"
