{"cve":"CVE-2018-4888","nvd":{"published":"2018-02-27T05:29:00.843","modified":"2026-06-17T01:59:13.660","status":"Modified","description":"An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability is an instance of a use after free vulnerability. The vulnerability is triggered by a crafted PDF file that can cause a memory access violation exception in the XFA engine because of a dangling reference left as a consequence of freeing an object in the computation that manipulates internal nodes in a graph representation of a document object model used in XFA. Successful exploitation could lead to arbitrary code execution.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-416"],"references":["http://www.securityfocus.com/bid/102995","http://www.securitytracker.com/id/1040364","https://helpx.adobe.com/security/products/acrobat/apsb18-02.html","http://www.securityfocus.com/bid/102995","http://www.securitytracker.com/id/1040364"],"products":["adobe:acrobat","adobe:acrobat_dc","adobe:acrobat_reader","adobe:acrobat_reader_dc"],"source":"nvd","synced_at":"2026-10-19T20:48:34.567387330+00:00"},"epss":{"cve":"CVE-2018-4888","score":0.12236,"percentile":0.96174,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
