{"id":"CVE-2026-40503","summary":"OpenHarness Path Traversal Information Disclosure via /memory show","details":"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.","modified":"2026-07-16T03:31:05.600766056Z","published":"2026-04-16T00:08:09.535Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40503.json","unresolved_ranges":[{"extracted_events":[{"fixed":"dd1d235450dd987b20bff01b7bfb02fe8620a0af"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40503.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40503"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openharness-path-traversal-information-disclosure-via-memory-show"},{"type":"REPORT","url":"https://github.com/HKUDS/OpenHarness/pull/127"},{"type":"FIX","url":"https://github.com/HKUDS/OpenHarness/commit/dd1d235450dd987b20bff01b7bfb02fe8620a0af"},{"type":"PACKAGE","url":"https://github.com/HKUDS/OpenHarness"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hkuds/openharness","events":[{"introduced":"0"},{"fixed":"dd1d235450dd987b20bff01b7bfb02fe8620a0af"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v0.1.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40503.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
