An unauthenticated attacker can embed malicious JavaScript that will run in the browser of any visitor that loads a gallery page.

The vulnerability is not listed in the CISA KEV catalog, which reduces concern about active exploitation campaigns. Attackers can invoke the flaw through a crafted URL or form input that is reflected by the plugin, making the attack vector public and straightforward for unauthenticated users. If exploited, it can lead to user\u2011side script execution, compromising the security of visitors rather than the server itself."}}}}, "created": "2025-08-05T11:39:03.899791+00:00", "updated": "2026-04-20T20:15:06.215420+00:00", "vendors": ["aumsrini", "aumsrini$PRODUCT$image_gallery", "wordpress", "wordpress$PRODUCT$wordpress"]}
