Details

The Timeline Block – Beautiful Timeline Builder for WordPress (Vertical & Horizontal Timelines) plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.3.3 via the tlgb_shortcode() function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to disclose private timeline content via the id attribute supplied to the 'timeline_block' shortcode.

Severity ?

4.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
