A second boundary parameter is then not reported as a duplicate, and MIME::Parser splits the message on it.\n\nReaders that skip comments as RFC 5322 allows take the first boundary instead. A remote sender can hide an attachment from a filter that relies on ambiguous_content() while the recipient's mail client shows it.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116272","source_modified_at":"2026-10-28T17:34:25.862Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":null,"vendor":null,"versions":[{"lessThan":"5.521","status":"affected","version":"0","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116272","source_modified_at":"2026-10-28T17:34:25.862Z","fetched_at":"2026-10-28T20:58:01.013507Z","package":{"name":null,"ecosystem":null},"version":"5.521","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T17:34:25.862Z","modified_at":"2026-10-28T17:34:25.862Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116272","fetched_at":"2026-10-28T20:58:01.013507Z","source_modified_at":"2026-10-28T17:34:25.862Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://metacpan.org/release/DSKOLL/MIME-tools-5.521/changes","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T17:34:25.862Z","content_hash":"ab199fab9bdb04255d273ad9eee3cd07ee5e73f4c8eb6bdd4c1dfa74274b3cb2"}}
