CVE-2026-40503: Hkuds Openharness

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

OpenHarness prior to commit dd1d235 contains a path traversal vulnerability that allows remote gateway users with chat access to read arbitrary files by supplying path traversal sequences to the /memory show slash command. Attackers can manipulate the path input parameter to escape the project memory directory and access sensitive files accessible to the OpenHarness process without filesystem containment validation.
