{"id":"CVE-2026-82864","summary":"pdfme pdf-lib before 5.5.10 Denial of Service via Decompression Bomb","details":"pdfme pdf-lib versions before 5.5.10 contain an unbounded buffer growth vulnerability in the DecodeStream.ensureBuffer() method that allows attackers to cause denial of service by supplying a crafted PDF with a FlateDecode stream containing a decompression bomb. 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.","aliases":["GHSA-vrqm-gvq7-rrwh"],"modified":"2026-09-02T03:47:23.276460665Z","published":"2026-08-31T08:46:35.269Z","database_specific":{"cwe_ids":["CWE-409"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82864.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/82xxx/CVE-2026-82864.json"},{"type":"ADVISORY","url":"https://github.com/pdfme/pdfme/security/advisories/GHSA-vrqm-gvq7-rrwh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82864"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/pdfme-pdf-lib-before-5.5.10-denial-of-service-via-decompression-bomb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pdfme/pdfme","events":[{"introduced":"0"},{"fixed":"f838f252ded53c52b2fcfd072c12f3c6ff68782c"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"5.5.10"}]}}],"versions":["5.5.8","5.5.7","5.5.6","5.5.5","5.5.4","5.5.3","5.5.2","5.5.1","5.5.0","5.4.8","5.4.7","5.4.6","5.4.4","5.4.3","5.4.2","5.4.1","5.4.0","5.3.19","5.3.18","5.3.17","5.3.16","5.3.15","5.3.14","5.3.13","5.3.12","5.3.11","5.3.10","5.3.9","5.3.8","5.3.7","5.3.6","5.3.5","5.3.4","5.3.3","5.3.2","5.3.1","5.3.0-beta.0","5.3.0","5.2.16","5.2.15","5.2.14","5.2.13","5.2.12","5.2.11","5.2.10","5.2.9","5.2.8","5.2.7","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2.0","5.1.7","5.1.6","5.1.5","5.1.4","5.1.3","5.1.2","5.1.1","5.1.0","5.0.0","4.5.2","4.5.1","4.5.0","4.4.2","4.4.1","4.4.0","4.3.2","4.3.1","4.3.0","4.2.5","4.2.4","4.2.3","4.2.2","4.2.1","4.2.0","4.1.1","4.1.0","4.0.2","4.0.0","3.4.3","3.4.2","3.4.1","3.4.0","3.3.0","3.2.3","3.2.2","3.2.1","3.2.0","3.1.5","3.1.3","3.1.2","3.1.1","3.1.0","3.0.1","3.0.0-beta.2","2.2.1","2.2.0","2.0.2","2.0.1","2.0.0","1.2.6","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0","1.1.9","1.1.7","1.1.5","1.1.4","1.1.3","1.1.2","1.1.1","1.0.18","1.0.17","1.0.16","1.0.15","1.0.14","1.0.13","1.0.12","1.0.11","1.0.10","1.0.9","1.0.8","1.0.7","1.0.6","1.0.5","1.0.4","1.0.3","1.0.2","1.0.1","1.0.0","1.0.0-beta.11","1.0.0-beta.10","1.0.0-beta.9","1.0.0-beta.8","1.0.0-beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-82864.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
