The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/jhy/jsoup/commit/862ba2f1d48ee95609183dbcfc848c9fd7afc76a","https://github.com/jhy/jsoup/pull/2556","https://www.vulncheck.com/advisories/jsoup-uncontrolled-resource-consumption-in-xmltreebuilder"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-75140","score":0.00525,"percentile":0.44234,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-65r4-943x-97jj","url":"https://osv.dev/vulnerability/GHSA-65r4-943x-97jj","summary":"jsoup XmlTreeBuilder vulnerable to memory exhaustion through deeply nested namespace declarations","modified":"2026-10-05T22:45:05.710363586Z","packages":[{"ecosystem":"Maven","name":"org.jsoup:jsoup","purl":"pkg:maven/org.jsoup/jsoup","ranges":["<1.23.2"],"fixed":["1.23.2"]}]}],"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).
