"COMPLETED & SECURED" : "EXPLOITABLE / PENDING"} ======================================================================== 1. EXECUTIVE SUMMARY Based on security research involving forum image upload pipelines and AI integrations (e.g. Discourse libheif heap overflow leading to OpenAI ChatGPT account takeover vectors), this workbench inspected all image container chunks, metadata headers, and non-pixel embedded blocks. 2. DETECTED ANOMALIES & AUDIT LOG: ${activeState.findings.map(f => ` - [${f.status}] ${f.offset} | ${f.type} -> Impact: ${f.impact}`).join('\n')} 3. REMEDIATION PROTOCOL IMPLEMENTED: - Byte-level offset realignment of IHDR and container headers - Purged non-standard foreign blocks (including script payloads) - Isolated pixel bitstream through pure re-encoding - Pipeline verification against ImageMagick / libheif CVE mitigation benchmarks 4. RECOMMENDED UPSTREAM HARDENING: - Restrict accepted formats in ImageMagick policy.xml (disable unneeded HEIF/AVIF) - Run image decoding in ephemeral, isolated container sandboxes - Patch libheif to latest security backport (>= v1.23.4) ======================================================================== Generated by Super AI Image Exploit Sandbox (Slug: ai-image-exploit-sandbox-90) `; const blob = new Blob([report], { type: 'text/plain' }); const filename = `security_report_${activeState.filename.replace(/\.[^/.]+$/, "")}.txt`; const link = document.createElement('a'); link.href = URL.createObjectURL(blob); link.download = filename; document.body.appendChild(link); link.click(); document.body.removeChild(link); URL.revokeObjectURL(link.href); const fb = document.getElementById('export-feedback'); fb.style.display = 'block'; fb.innerText = `✓ Downloaded diagnostic report: ${filename}`; } // Custom File Upload Simulation document.getElementById('custom-file-input').addEventListener('change', function(e) { const file = e.target.files[0]; if (!file) return; activeState = { filename: file.name, targetParser: "Discourse Forum / Custom AI Pipeline", fileSize: `${(file.size / 1024).toFixed(1)} KB`, riskScore: 65, anomaliesCount: 1, payloadsCount: 1, sanitized: false, findings: [ { offset: "0x00000008", type: "Untrusted Header Magic Bytes", impact: "Potential parser confusion", status: "ANOMALY", badge: "tag-warn" }, { offset: "0x00000104", type: "Non-standard Metadata Segment", impact: "Possible script/binary injection", status: "SUSPICIOUS", badge: "tag-warn" } ], hexStream: `00000000: 89 50 4E 47 0D 0A 1A 0A 00 00 00 0D 49 48 44 52 00000010: [CUSTOM FILE STREAM DETECTED: ${file.name}] 00000040: Parsing header segments... flagged non-standard metadata tags.` }; document.querySelectorAll('.preset-btn').forEach(btn => btn.classList.remove('active')); document.getElementById('export-feedback').style.display = 'none'; updateUI(); }); // Boot execution window.addEventListener('DOMContentLoaded', () => { initFabric(); updateUI(); }); window.addEventListener('resize', () => { renderPipelineGraph(); });
