# Safe Codex Prompt: CVE-2026-21833

Prepare a defensive remediation plan for CVE-2026-21833.

Use only the public-safe context below unless the user separately provides repo context.

Source summary: NVD: HCL AION is affected by a vulnerability in which the Content-Security-Policy (CSP) HTTP response header is not configured. NVD: CSP helps prevent attacks such as Cross-Site Scripting (XSS) by restricting the sources from which scripts, styles, and other resources can be loaded. NVD: 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.
Affected vendor/product: unknown / unknown
Risk context: {'severity': 'LOW', 'cvss_score': 3.7, 'cvss_label': 'LOW', 'epss_percentile': 0.09569, 'kev_status': 'not_listed', 'risk_flags': ['official reference present']}
Remediation context: {'recommended_route': 'vendor_patch_or_mitigation', 'reference_status': 'official_reference_present', 'patch_status': 'requires_confirmation', 'fixed_versions': [], 'mitigation_notes': ['Remediation reference present; patch status requires confirmation in the linked advisory.', 'Patch status requires confirmation from the linked advisory or official source.']}

Human checklist:
- Confirm whether the listed product or package is present.
- Confirm affected version.
- Review vendor advisory or official source.
- Confirm patch, fixed version, mitigation, workaround, or monitor-only decision.
- Confirm exposure.
- Document remediation status.

Allowed actions:
- summarize vendor guidance
- prepare a defensive remediation plan
- identify affected dependencies only when repo context is separately provided by the user
- suggest tests and validation steps
- document human verification questions

Disallowed actions:
- generate offensive code
- provide payloads
- scan external targets
- change production systems
- merge or deploy changes
- create GitHub issues or pull requests without explicit separate approval

Acceptance criteria:
- Affected product or dependency presence is confirmed by a human.
- Affected version is confirmed or marked not applicable.
- Official advisory or source reference is reviewed.
- Patch, fixed version, mitigation, workaround, or monitor-only decision is documented.
- Validation steps are proposed without external scanning or production mutation.
