Attackers can upload a small compressed PDF that decompresses to hundreds of megabytes, exhausting memory and crashing the Node.js process or freezing browser tabs during PDF parsing.","state":0,"publishedAt":"2026-08-31T08:46:35.269+00:00","modifiedAt":"2026-10-08T15:25:39.287+00:00","affected":[{"ecosystem":"Vendor product","name":"pdf-lib","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pdfme\",\n                    \"product\": \"pdf-lib\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/%40pdfme/pdf-lib\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"5.5.10\"\n                        },\n                        {\n                            \"version\": \"5.5.10\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/pdfme/pdfme/security/advisories/GHSA-vrqm-gvq7-rrwh","https://www.vulncheck.com/advisories/pdfme-pdf-lib-before-5.5.10-denial-of-service-via-decompression-bomb"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-82864","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-82864","identifiers":["CVE-2026-82864"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
