Attackers can craft ZIP archives where getEntry() or readAsText() validates benign content while extractAllTo() writes malicious content to the same path, bypassing integrity checks.","categories":["Unclassified"],"product":"adm-zip","vendor":"cthackers","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116137","source_modified_at":"2026-10-25T11:51:01.980Z","fetched_at":"2026-10-25T16:01:37.004770Z","product":"adm-zip","vendor":"cthackers","versions":[{"version":"0","status":"affected","versionType":"semver","lessThanOrEqual":"0.6.1"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-25T11:51:01.980Z","modified_at":"2026-10-25T11:51:01.980Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116137","fetched_at":"2026-10-25T16:01:37.004770Z","source_modified_at":"2026-10-25T11:51:01.980Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/cthackers/adm-zip/issues/587","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/cthackers/adm-zip","tags":["product"]},{"source":"CVE List","url":"https://github.com/cthackers/adm-zip/blob/cb2cf9ba4c7c865db426e2de1997cb41194d9872/zipFile.js#L81-L92","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/cthackers/adm-zip/blob/cb2cf9ba4c7c865db426e2de1997cb41194d9872/adm-zip.js#L87","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/cthackers/adm-zip/blob/cb2cf9ba4c7c865db426e2de1997cb41194d9872/util/utils.js#L383","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/adm-zip-through-0.6.1-duplicate-entry-validation-bypass-via-canonically-equivalent-names","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-25T11:51:01.980Z","content_hash":"39b751413d2549adf9385fd8b7e96219056ba11f16679ad8723ee0763f32c0a8"}}
