Embedded resource references in the fetched HTML (e.g. `<img src=\"http://169.254.169.254/...\">`) are fetched by WeasyPrint with no per-resource SSRF filtering, allowing an attacker-controlled page to cause the server to retrieve cloud metadata endpoints or internal network resources and leak their contents back into the generated PDF."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-918", "cweId": "CWE-918", "type": "CWE"}]}], "affected": [{"vendor": "Stirling-Tools", "product": "Stirling-PDF", "programFiles": ["app/core/src/main/java/stirling/software/SPDF/controller/api/converters/ConvertWebsiteToPDF.java"], "versions": [{"version": "0", "lessThanOrEqual": "*", "status": "affected", "versionType": "custom"}], "defaultStatus": "unaffected"}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N", "baseScore": 8.6, "baseSeverity": "HIGH"}}], "references": [{"url": "https://github.com/Stirling-Tools/Stirling-PDF"}], "credits": [{"lang": "en", "value": "Alibek Baxtiyorov", "type": "finder"}], "providerMetadata": {"orgId": "309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c", "shortName": "TuranSec", "dateUpdated": "2026-08-05T12:26:17.631Z"}}}}
