after further discussion, upstream issued a new fix which reverts previous commits
https://github.com/Cacti/cacti/commit/cfb0733597af97abc92270de4f47cbfa32f9ce8b (release/1.2.8)
which turned out to be insufficient to fix the issue, follow up patches:

The original issue mentions only a bypass via graph_json.php but there are
additional permission checks missed while checking the issue fixed with the
upstream commits.
