Malicious packageFind it
Search your lockfiles and build artifacts for @douinfe/semi-theme-default (version 9.3.5).
If you installed it — respond
Remove @douinfe/semi-theme-default from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @douinfe/semi-theme-default was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
