An attacker with CMS credentials can upload a specially crafted SVG file that contains malicious JavaScript.

The EPSS score is less than 1\u202f%, implying a very low public exploitation probability. The vulnerability is not listed in CISA\u2019s KEV catalog. Exploitation requires authenticated access to the CMS to upload the SVG file and a subsequent user interaction with the link. Thus the threat is confined to privileged uploaders or attackers who have obtained legitimate CMS credentials. As no public exploit has been reported, the immediate risk is low, but the potential impact remains high if an attacker compromises a user account."}}}}, "created": "2026-03-02T12:07:20.438257+00:00", "updated": "2026-04-17T14:15:21.779929+00:00", "vendors": ["pluxml", "pluxml$PRODUCT$pluxml"]}
