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.","categories":["Applications & CMS"],"product":"AION","vendor":"HCL Software","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-21833","source_modified_at":"2026-10-01T18:03:33.734Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"AION","vendor":"HCL Software","versions":[{"status":"affected","version":"Version 2.5.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":3.7,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00205,"percentile":0.09925,"score_date":"2026-10-23"},"published_at":"2026-10-01T16:54:24.057Z","modified_at":"2026-10-01T18:03:33.734Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-21833","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T18:03:33.734Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-21833","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0134082"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-01T18:03:22.825890Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-01T18:03:33.734Z","content_hash":"0c7aff3225f68f2ca8754ca1dbf42b5d39a0a6bc8a6f314c697fa3db71c49c6c"}}
