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.","state":0,"publishedAt":"2026-10-01T16:54:24.057+00:00","modifiedAt":"2026-10-01T18:03:33.734+00:00","affected":[{"ecosystem":"Vendor product","name":"AION","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"HCL Software\",\n                    \"product\": \"AION\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"Version 2.5.0\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7,"severity":"LOW"}],"references":["https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0134082"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-21833","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-21833","identifiers":["CVE-2026-21833"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
