EventON Lite <= 2.4.7 - Authenticated (Contributor+) Information Disclosure

EventON – Events Calendar: Currently marked unpatched

Affected versions: *-2.4.7

Vulnerability type: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor

Affected software, patched versions and attribution

The EventON Lite plugin for WordPress is vulnerable to Information Exposure in all versions less than, or equal to, 2.4.6 via the add_single_eventon and add_eventon shortcodes due to insufficient restrictions on which posts can be included.

EventON – Events Calendar: Currently marked unpatched

Affected versions: *-2.4.1

Vulnerability type: CWE-98 Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')

Affected software, patched versions and attribution

The EventON plugin for WordPress is vulnerable to Local File Inclusion via the evo_block_render_callback() function in versions up to, and including, 2.4.1.
