Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
maintainer-change maintainer-added AI (maintainer-change): xhmikosr is a known imagemin org contributor; addition is consistent with legitimate open-source project maintenance. ai
provenance no-provenance AI (provenance): Established imagemin ecosystem package; lack of Sigstore provenance is expected for packages of this age and does not indicate risk. ai
provenance publisher-changed AI (provenance): Known legitimate transfer from 1000ch to sindresorhus within the imagemin ecosystem in 2021; sindresorhus is a highly trusted publisher with extensive npm history. ai
semgrep semgrep:child-process-import AI (semgrep): child_process/spawn is used in cli.js to execute the mozjpeg binary — core purpose of this CLI wrapper package, not malicious. ai
install-scripts install-script:postinstall AI (install-scripts): mozjpeg is a binary wrapper package; postinstall running node lib/install.js to fetch/build the mozjpeg binary is the documented and expected install flow for this imagemin ecosystem package. ai
