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."}], "lastModified": "2026-10-02T18:47:49.947", "sourceIdentifier": "psirt@hcl.com"}
