KeePassXC: Heap use-after-free in KeePass1 (KDB) importer via unpruned m_entryUuids map
CVE-2026-69150 is fixed in 4 products on 3 platforms, first by KeePassXC 2.8.0, released October 21, 2026. It is not reported as exploited. Patch Radar priority: Routine.
KeePassXC is a cross-platform community-driven port of the Windows application KeePass Password Safe. Prior to 2.8.0-beta1, KeePass1 / KDB legacy import retains raw Entry pointers in m_entryUuids after deleting metastream entries. When a crafted, unlockable .kdb file contains an earlier metastream entry followed by a KPX_CUSTOM_ICONS_4 metastream that references the earlier UUID, parseCustomIcons4() calls Entry::setIcon through the stale pointer, causing a heap use-after-free with a controlled write and a reliable process crash. This issue is fixed in version 2.8.0-beta1.
