User::getTaggedSubscriptions()
This change escapes the $tag argument to prevent a SQL injection
attack in User::getTaggedSubscriptions(). The parameter was not
escaped higher up the stack, so this vulnerability could be exploited.
This change escapes the argument to User::getTaggedSubscribers() to
prevent SQL injection attacks.
Both code paths up the stack fail to escape this parameter, so this is
a potential SQL injection attack.
This patch escapes query parameters in Profile_tag::getTagged(). This
is an extra security step; since these parameters come out of the
database, it's unlikely that they would have dangerous data in them.
This change adds additional escapes for arguments to
Profile_tag::moveTag(). The arguments are canonicalized in the API and
Web UI paths higher up the stack, but this change makes sure that no
other paths can introduce SQL injection errors.
This patch escapes the $tag parameter in
Profile::getTaggedSubscribers(). The parameter is not escaped either
in actions/subscriptions.php or in actions/apiuserfollowers.php. So
there is a potential for SQL injection here.
This change escapes a parameter in Local_group::setNickname(). Review
of the code paths that call this function sanitize the parameter
higher up the stack, but it's escaped here to prevent mistakes later.
Note that nickname parameters are normally alphanum strings, so
there's not much danger in double-escaping them.
