CSP helps prevent attacks such as Cross-Site Scripting (XSS) by restricting the sources from which scripts, styles, and other resources can be loaded. The absence of this header may reduce the effectiveness of browser-based security controls, potentially resulting in unintended behavior or negative security impacts under certain conditions.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-1032"],"vendors":[],"products":[],"references":[{"url":"https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0134082","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
