CVE-2021-28918 — netmask CRITICAL (9.8)
CVSS: 9.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
CWE: CWE-704 (Incorrect Type Conversion)
CISA KEV: Not listed

What it is: netmask@1.0.6 improperly parses octal-notation IP addresses (e.g. 010.0.0.1),
treating them as decimal. This enables SSRF protection bypass and IP allowlist/blocklist
bypass — an attacker can craft an address that appears private but routes to a public host.

Exploit status: Not in CISA KEV. Public PoC exists (SICK-2021-011), ~280k affected projects.

Codebase exposure: netmask is not directly imported — it appears in package-lock.json as a
transitive dependency of pac-resolver@3.0.0 (a transitive dev dependency). No direct
require('netmask') or IP parsing logic found. Reachability is very low.

Recommendation: Upgrade — low effort, patch version (1.0.6 → 1.1.0), no API changes.
netmask is a transitive dependency; use npm audit fix or add a package.json overrides entry
to force netmask@1.1.0.
