CVE-2018-15833
In Vanilla before 2.6.1, the polling functionality allows Insecure Direct Object Reference (IDOR) via the Poll ID, leading to the ability of a single user to select multiple Poll Options (e.g., vote for multiple items).
Does this matter?
Lower severity and a low EPSS score (0.88%). Track it; it rarely justifies an emergency change on its own.
