What is CVE-2026-14833?

The Lightbox with PhotoSwipe plugin for WordPress, prior to version 5.9.0, introduces a security flaw that fails to properly sanitize or escape link data attributes in the image lightbox caption. This oversight permits users with author-level access or higher, who typically lack the unfiltered_html capability, to inject malicious JavaScript. When a visitor or administrator interacts with the lightbox, the stored JavaScript can execute, potentially compromising website security and user data.

Affected Version(s)

Lightbox with PhotoSwipe 0 < 5.9.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
