Any WordPress installation running ZoomSounds 6.91 or earlier is at risk.", "description_and_impact": "The ZoomSounds WordPress plugin contains a stored cross\u2011site scripting (XSS) flaw that originates from insufficient sanitization of user-supplied attributes in shortcodes. An authenticated user with contributor\u2011level or higher privileges can inject arbitrary JavaScript into a generated page via a crafted shortcode. When another site visitor loads that page, the injected script runs in their browser, potentially stealing session cookies, defacing the site, or redirecting the user to malicious sites. The impact is a loss of confidentiality and integrity for all users who view the affected pages.", "risk_and_exploitability": "With a CVSS score of 6.4, the flaw rates as medium severity, and an EPSS score of less than 1\u202f% indicates a low probability of exploitation. The vulnerability is not listed in CISA\u2019s KEV catalog. It requires an authenticated user with at least contributor rights to inject the malicious shortcode, so the attack vector is an authenticated web\u2011application access scenario. Although exploitation is unlikely, the potential impact of a successful XSS makes this a serious concern for any site using affected versions."}}}}, "created": "2026-04-22T13:30:17.926829+00:00", "updated": "2026-04-22T13:30:17.926844+00:00", "vendors": []}
