Users with Contributor\u2011level access or higher can exploit this flaw.\n", "description_and_impact": "The Phlox theme for WordPress contains a stored cross\u2011site scripting flaw that allows an authenticated user with Contributor or higher privileges to inject arbitrary JavaScript into the page via the data\u2011caption attribute. The injected script is rendered and executed when any visitor loads the affected page, enabling attackers to hijack user sessions, exfiltrate data, deface content, or redirect users to malicious sites. The weakness is a classic input validation and output escaping failure cataloged as CWE\u201179.", "risk_and_exploitability": "The vulnerability is assigned a CVSS score of 6.4, indicating moderate severity, and has an EPSS score of less than 1\u202f%, suggesting a low probability of exploitation in the wild. The flaw is not listed in the CISA KEV catalog. Exploitation requires the attacker to be authenticated with at least Contributor permissions, so lateral movement into content editing is a prerequisite. Once achieved, the attacker can embed malicious scripts that execute in any visitor\u2019s browser, making the danger particularly high within high\u2011traffic sites."}}}}, "created": "2026-01-06T14:15:50.790329+00:00", "updated": "2026-04-20T21:30:18.566061+00:00", "vendors": ["averta", "averta$PRODUCT$phlox", "wordpress", "wordpress$PRODUCT$wordpress"]}
