{"id":"CVE-2026-112049","summary":"Vita3K before build 4187 Path Traversal via VPK Package Installation","details":"Vita3K before build 4187 contains a path traversal (zip slip) vulnerability in install_archive_content() that allows attackers to write files outside the install directory via crafted .vpk archives. Attackers can embed '..' segments or absolute paths in zip entry names to write attacker-controlled files anywhere writable by Vita3K, potentially enabling host code execution.","modified":"2026-10-21T09:43:34.276361038Z","published":"2026-10-18T12:19:40.323Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112049.json","unresolved_ranges":[{"extracted_events":[{"range":[{"fixed":"4187"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]}],"cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112049.json"},{"type":"PACKAGE","url":"https://github.com/Vita3K/Vita3K"},{"type":"ARTICLE","url":"https://github.com/Vita3K/Vita3K/blob/f0273e4cd9b860ea77c44c73d9f5c5b1ed5fa8ab/vita3k/interface.cpp#L219-L234"},{"type":"FIX","url":"https://github.com/Vita3K/Vita3K/commit/55f88cd17a78ce8af7d753c7c4eb2f709f7d6dbc"},{"type":"REPORT","url":"https://github.com/Vita3K/Vita3K/issues/4254"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112049"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/vita3k-before-build-4187-path-traversal-via-vpk-package-installation"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vita3k/vita3k","events":[{"introduced":"0"},{"fixed":"55f88cd17a78ce8af7d753c7c4eb2f709f7d6dbc"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"55f88cd17a78ce8af7d753c7c4eb2f709f7d6dbc"}],"source":"REFERENCES_COMMIT"}]}}],"database_specific":{"vanir_signatures":[{"source":"https://github.com/vita3k/vita3k/commit/55f88cd17a78ce8af7d753c7c4eb2f709f7d6dbc","target":{"file":"vita3k/interface.cpp"},"deprecated":false,"digest":{"line_hashes":["120334593134009433659114190486843016922","314360981252536962145781578899384265078","194436739296813237419718491373347042630","227638362302509377140030343809613975263"],"threshold":0.9},"id":"CVE-2026-112049-4b944eb8","signature_type":"Line","signature_version":"v1"}],"vanir_signatures_modified":"2026-10-21T09:43:34Z","source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112049.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
