The vulnerability arises from unsanitized output in Twig templates and JavaScript literal interpolation, allowing script execution in the context of any browser that views pages containing those entities. The weakness is a classic stored cross\u2011site scripting flaw, classified as CWE-79, which can lead to session hijacking, credential theft, defacement, or further exploitation of users who visit affected pages.", "risk_and_exploitability": "The vulnerability carries a CVSS score of 4.8, indicating moderate severity. Its EPSS score is below 1%, suggesting low probability of widespread exploitation at present, and it is not listed in the CISA KEV catalog. However, because an attacker must be authenticated to inject payloads, the attack surface is limited to privileged users. Once injected, the script executes in the browsers of all users who view pages that render the compromised entity, allowing attackers to steal session cookies or hijack accounts. The official Fixes are available, so the risk drops to negligible once the system is updated."}}}}, "created": "2026-03-11T11:39:20.757867+00:00", "updated": "2026-04-16T03:15:22.948526+00:00", "vendors": ["sylius", "sylius$PRODUCT$sylius"]}
