pixsvgnpm
pixsvg is a confirmed malicious npm package (MAL-2026-17313) that executes malicious code on install (malicious version 0.2.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in pixsvg (npm)
What this malware does
The pixsvg module exports fetchDataFromSvg(svgData), which scans the input SVG for a comment of the form <!--HIDDEN_JS:([01]+)-->, reassembles the binary-encoded 1/0 sequence into a JavaScript string via binaryToData (parseInt(chunk,2) + String.fromCharCode), and passes the reconstructed string to eval(). The helper is exported on the package's public surface (module.exports.fetchDataFromSvg) but is not documented in the README and is unrelated to the advertised SVG image pipeline. Any consumer application that feeds externally-supplied SVG content through this exported function will execute attacker-controlled JavaScript in the host process. The binary-encoding-then-eval shape is a deliberate covert execution channel with no legitimate role in an image-processing library.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for pixsvg (version 0.2.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging pixsvg across your stack and pipelines.
If you installed it — respond
Remove pixsvg 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 pixsvg was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks pixsvg before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Detect & block this
O3 blocks pixsvg-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
