When a client sends PROT P after PASV or PORT, file contents and directory listings cross the network unencrypted, even with mandatory encryption, letting on-path attackers read or modify them.","categories":["Unclassified"],"product":"ftpserverlib","vendor":"fclairamb","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116844","source_modified_at":"2026-10-27T00:34:02.373Z","fetched_at":"2026-10-27T04:51:10.072820Z","product":"ftpserverlib","vendor":"fclairamb","versions":[{"version":"0","status":"affected","versionType":"semver","lessThanOrEqual":"0.32.4"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T00:34:02.373Z","modified_at":"2026-10-27T00:34:02.373Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116844","fetched_at":"2026-10-27T04:51:10.072820Z","source_modified_at":"2026-10-27T00:34:02.373Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/fclairamb/ftpserverlib/pull/685","tags":["patch","issue-tracking"]},{"source":"CVE List","url":"https://github.com/fclairamb/ftpserverlib/blob/v0.32.4/handle_misc.go#L29-L31","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/fclairamb/ftpserverlib/blob/v0.32.4/client_handler.go#L720","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/fclairamb-ftpserverlib-through-0.32.4-cleartext-ftpes-data-transfer-via-prot-p","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":"2026-10-27T00:34:02.373Z","content_hash":"e1215a6200e9dd357d962556a7bf263f8e194e2ab84d7f91e6e97c5311511960"}}
