This package is used to read TNEF files (Microsoft Outlook and Microsoft Exchange Server). If an application uses poi-scratchpad to parse TNEF files and the application allows untrusted users to supply them, then a carefully crafted file can cause an Out of Memory exception. This issue affects poi-scratchpad version 5.2.0 and prior versions. Users are recommended to upgrade to poi-scratchpad 5.2.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-20","CWE-770"],"references":["https://lists.apache.org/thread/sprg0kq986pc2271dc3v2oxb1f9qx09j","https://security.netapp.com/advisory/ntap-20221028-0006/","https://lists.apache.org/thread/sprg0kq986pc2271dc3v2oxb1f9qx09j","https://security.netapp.com/advisory/ntap-20221028-0006/"],"products":["apache:poi","netapp:active_iq_unified_manager"],"source":"nvd","synced_at":"2026-10-19T21:28:04.509275555+00:00"},"epss":{"cve":"CVE-2022-26336","score":0.01526,"percentile":0.74686,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mqvp-7rrg-9jxc","url":"https://osv.dev/vulnerability/GHSA-mqvp-7rrg-9jxc","summary":"Improper Input Validation and Allocation of Resources Without Limits or Throttling in poi-scratchpad","modified":"2024-05-15T07:02:06.818374Z","packages":[{"ecosystem":"Maven","name":"org.apache.poi:poi-scratchpad","purl":"pkg:maven/org.apache.poi/poi-scratchpad","ranges":[">=3.8-beta1 <5.2.1"],"fixed":["5.2.1"]}]}],"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).
