CVE-2023-29100Network attack vector

Unauthenticated XSS via DT Flickr widget

Published Jun 23, 2023 · Updated Apr 28, 2026

Reflected cross-site scripting in Dream-Theme The7 through 11.6.0 allows remote attackers to execute script in a victim browser via a crafted link. The legacy DT Flickr widget insufficiently sanitizes input and fails to escape reflected output, allowing attacker-controlled script to reach the rendered page. Exploitation requires an unauthenticated attacker to induce a user to follow the malicious link; impact is limited to actions available in that victim browser context.
