Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:base64-decode AI (semgrep): Base64 decode is used for OOXML encryption salt handling in exceljs encryptor — legitimate cryptographic use, not obfuscation. ai
phantom-deps phantom-dep:@types/node AI (phantom-deps): @types/node as a runtime dep is a known exceljs pattern; framework-scoped type package, not a real phantom dep concern. ai
