At a glance

CVE-2019-15779 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Social Feed Gallery WordPress plugin, affecting versions < 2.4.8. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.4.8; sites on affected versions should update now. Disclosed August 2019.

Vulnerability Overview

The insta-gallery plugin before 2.4.8 for WordPress has no nonce validation for qligg_dismiss_notice or qligg_form_item_delete.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Social Feed Gallery < 2.4.8 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Social Feed Gallery the fix is 2.4.8: builds < 2.4.8 are affected, anything from 2.4.8 onward is not.

Remediation

Update to version 2.4.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Social Feed Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Social Feed Gallery 2.4.8 closes this, and updating the plugin is the step that ends it.
