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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Exploit Intelligence, Migration Toolkit for Applications 8, OpenShift Developer Tools and Services, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · no fix planned: Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat JBoss Enterprise Application Platform 7, Red Hat OpenStack Platform 13 (Queens), … · updated 2026-10-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-75140.json)\n- **RHSA-2026:69470** · Red Hat · fixed in: Red Hat build of Quarkus 3.27.5.SP2 · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69470)\n- **RHSA-2026:69440** · Red Hat · fixed in: Red Hat build of Quarkus 3.33.3.SP2 · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69440)\n\n## Package advisory (CVE-2026-75140)\n\nAffected packages:\n\n- `org.jsoup:jsoup < 1.23.2`\n\nPatched in:\n\n- `org.jsoup:jsoup 1.23.2`\n\nSource: https://github.com/advisories/GHSA-65r4-943x-97jj","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
