The issue affects the parsing of OOXML format files like xlsx, docx and pptx. These file formats are basically zip files and it is possible for malicious users to add zip entries with duplicate names (including the path) in the zip. In this case, products reading the affected file could read different data because 1 of the zip entries with the duplicate name is selected over another but different products may choose a different zip entry.\nThis issue affects Apache POI poi-ooxml before 5.4.0. poi-ooxml 5.4.0 has a check that throws an exception if zip entries with duplicate file names are found in the input file.\nUsers are recommended to upgrade to version poi-ooxml 5.4.0, which fixes the issue. Please read  https://poi.apache.org/security.html  for recommendations about how to use the POI libraries securely.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-20"],"references":["https://bz.apache.org/bugzilla/show_bug.cgi?id=69620","https://lists.apache.org/thread/k14w8vcjqy4h34hh5kzldko78kpylkq5","http://www.openwall.com/lists/oss-security/2025/04/08/2","https://security.netapp.com/advisory/ntap-20250523-0004/"],"products":["apache:poi","netapp:active_iq_unified_manager"],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-31672","score":0.01355,"percentile":0.71623,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gmg8-593g-7mv3","url":"https://osv.dev/vulnerability/GHSA-gmg8-593g-7mv3","summary":"Apache POI OOXML Vulnerable to Improper Input Validation in OOXML File Parsing","modified":"2026-09-10T03:50:23.912462504Z","packages":[{"ecosystem":"Maven","name":"org.apache.poi:poi-ooxml","purl":"pkg:maven/org.apache.poi/poi-ooxml","ranges":["<5.4.0"],"fixed":["5.4.0"]}]}],"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).
