{"id":"CVE-2026-14683","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-14683","generatedAt":"2026-10-28T02:22:55.860Z","title":"A vulnerability was detected in HdrHistogram up to 2.2.2.","description":"A vulnerability was detected in HdrHistogram up to 2.2.2. Affected by this issue is the function org.HdrHistogram.AbstractHistogram.decodeFromCompressedByteBuffer of the file src/main/java/org/HdrHistogram/AbstractHistogram.java. The manipulation of the argument lengthOfCompressedContents results in uncontrolled memory allocation. The attack needs to be approached locally. The exploit is now public and may be used. It is still unclear if this vulnerability genuinely exists. This issue is disputed due to the potential lack of crossing of security boundaries and the pre-requisites for a successful attack.","published":"2026-07-04T23:16:56.000Z","lastModified":"2026-07-16T08:16:17.000Z","status":"Deferred","sourceIdentifier":"cna@vuldb.com","cvss":{"version":"4.0","score":1.9,"severity":"LOW","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-400","CWE-789"],"affected":[],"epss":{"score":0.0016,"percentile":0.0512,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.16%).
