 # Excluded because:
-# - Arbitrary code execution in protobufjs via malicious protobuf definition files (severity: critical)
-# - Affects protobufjs < 7.5.5; installed versions: 6.11.4 (@cosmjs/stargate), 7.2.5 (@hashgraph/sdk,
-#   sdk-coin-islm, sdk-coin-trx, sdk-coin-hbar), 7.5.4 (abstract-cosmos, sdk-coin-icp)
-# - Exploitation requires attacker-controlled .proto definition files; all protobuf definitions in this
-#   repo are static files bundled within trusted upstream dependencies — not user-supplied
-# - Versions 6.11.4 and 7.2.5 are pinned by upstream deps (@cosmjs ~6.11.x, @hashgraph/sdk 7.2.5)
-#   that do not yet support 7.5.5

-# Excluded because:
-# - DoS via memory exhaustion in basic-ftp <= 5.2.2 (severity: high, CVSS 7.5)
-# - Client.list() buffers entire directory listings without size limits; a malicious FTP server
-#   can send unbounded data to exhaust client memory
-# - Transitive dependency through pac-proxy-agent > get-uri > basic-ftp; used for PAC-based
-#   proxy resolution, not direct FTP operations
-# - Exploitation requires connecting to a malicious FTP server; all proxy targets in this
-#   project are controlled internal endpoints, not user-supplied FTP URLs
-# - Pinned at 5.2.2 in root resolutions; upstream get-uri has not yet updated to require 5.3.0

+# - XSS via xmp raw-text passthrough in sanitize-html (severity: critical, CVE-2026-44990)
+# - patched_versions: "<0.0.0" — no upstream fix exists yet
+# - Used in @bitgo/sdk-api to strip all HTML from API error response text (allowedTags: [])
+# - Output is appended to a JavaScript error string server-side, never rendered as HTML in a browser
+# - The xmp bypass produces live HTML markup in output, but since we discard all tags and use
+#   the result as plain text in Error messages, there is no DOM rendering path and no XSS risk
