{"schema":"threatline.record/2","record":{"id":"CVE-2026-118174","aliases":[],"summary":"Displaying a message could load an attacker-chosen URL through an OpenPGP key attachment","details":"When a message containing an OpenPGP key attachment was displayed, Thunderbird automatically loaded the attachment's content to offer importing the key. A sender could mark the attachment as an external attachment pointing to an arbitrary URL, which Thunderbird then loaded without any user interaction, bypassing remote content blocking. On Windows, a URL pointing to an attacker-controlled network share could leak the user's NTLM credentials.\nThe NTLM credential leak only affects Thunderbird on Windows. On other operating systems, the issue allowed a remote request that bypassed remote content blocking. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.","categories":["Unclassified"],"product":"Thunderbird","vendor":"Mozilla","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-118174","source_modified_at":"2026-10-27T18:27:46.521Z","fetched_at":"2026-10-27T21:14:11.489891Z","product":"Thunderbird","vendor":"Mozilla","versions":[{"status":"unaffected","version":"153.6","lessThanOrEqual":"153.*","versionType":"rpm"},{"status":"unaffected","version":"159","lessThanOrEqual":"*","versionType":"rpm"}],"defaultStatus":null}],"fixed_versions":[],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T18:16:28.729Z","modified_at":"2026-10-27T18:27:46.521Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-118174","fetched_at":"2026-10-27T21:14:11.489891Z","source_modified_at":"2026-10-27T18:27:46.521Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=2080910"},{"source":"CVE List","url":"https://www.mozilla.org/security/advisories/mfsa2026-121/"},{"source":"CVE List","url":"https://www.mozilla.org/security/advisories/mfsa2026-122/"}],"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":"2026-10-27T18:27:46.521Z","content_hash":"e8381da1c32b6490101b45ba6531be2862553d770cf4fd6819a34837c8698dff"}}
