The flaw arises from insufficient input sanitization and output escaping, allowing an attacker to inject arbitrary JavaScript. When the affected content is viewed, the injected script executes in the visitor\u2019s browser. This corruption is strictly client\u2011side; the vulnerability does not directly compromise server\u2011side code or data.", "risk_and_exploitability": "The CVSS score of 6.4 indicates moderate severity. The EPSS score is reported as less than 1\u202f%, suggesting a low likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Based on the description, the attack vector is internal, requiring the attacker to be authenticated with Contributor\u2011level or higher access. Once authenticated, the attacker can use the vulnerable align field to inject and execute scripts, providing client\u2011side compromise but no direct server\u2011side impact."}}}}, "created": "2026-04-21T21:00:36.014505+00:00", "updated": "2026-04-21T21:00:36.014521+00:00", "vendors": []}
