{"id":"CVE-2018-4888","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-4888","generatedAt":"2026-10-28T22:19:56.722Z","title":"This vulnerability is an instance of a use after free vulnerability.","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.","published":"2018-02-27T05:29:01.000Z","lastModified":"2026-06-17T01:59:14.000Z","status":"Modified","sourceIdentifier":"psirt@adobe.com","cvss":{"version":"3.0","score":8.8,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["adobe/acrobat","adobe/acrobat dc","adobe/acrobat reader","adobe/acrobat reader dc"],"epss":{"score":0.12236,"percentile":0.96153,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.08939,"percentile":0.95071},{"date":"2026-09-22","score":0.12236,"percentile":0.95988}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 12.2%, higher than 96% of all known CVEs.
