… generic rejections Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughDELIVERY.md adds guidance for package-publish failures caused by SQL-injection payload examples in README and CHANGELOG content. It documents the generic 403 response, incorrect diagnostic paths, and a probe-package bisection method. ChangesPublish-policy guidance
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk:🔵 Low · up to This PR adds publishing guidance based on an OTP-versus-403 diagnostic. The change is localized and does not affect runtime behavior, but the OTP inference should be scoped to this incident and documented with its registry, authentication flow, CLI version, and response codes; it is otherwise mergeable with owner follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

npm publish documentation one-time password prompt registry 2FA publish request content scanning order
💡 Result:
When using npm publish, the interaction between authentication, malware scanning, and registry requirements follows a specific flow designed for supply-chain security. 2FA and OTP Requirements Publishing to the npm registry requires either 2FA enabled on your account or the use of a granular access token with bypass 2FA enabled [1][2]. If 2FA is enabled (specifically in auth-and-writes mode), the registry will challenge the publish request for a one-time password (OTP) [3]. When a challenge is issued, the npm CLI behavior is as follows: - Interactive Environments: If you are running the command in a terminal (TTY), the CLI will detect the challenge and prompt you directly to enter the OTP [4][3]. - Providing OTP manually: You can bypass the prompt by providing the code via the --otp flag (e.g., npm publish --otp=123456) [5][4]. - Failure/Error Handling: If the provided OTP is incorrect, expired, or the CLI fails to detect the challenge, the publish operation will fail with an error [6][4][7]. Malware Scanning and Publish Order As of July 2026, npm automatically scans all newly published packages for malware [8][9]. This process is integrated into the publishing pipeline, occurring after the initial request reaches the registry [8][10]. 1. Submission: When you execute npm publish, the package is sent to the registry [8][11]. 2. Scanning: The registry performs automated static and dynamic analysis [10]. This typically introduces a delay of about 5 minutes, though it can take 15 minutes or longer during peak times [8][9]. 3. Availability: During the scan, the package is not yet installable [8]. Once the scan is complete, the package is published as normal, held for manual review, or blocked [8][9]. Dual-Use Content For packages containing security-relevant capabilities ("dual-use content"), specific requirements apply to maintain the integrity of the registry [12]: - Metadata: You must include a contentPolicy field in package.json and a DISCLOSURE file at the root of the package [8][9]. - 2FA Enforcement: Dual-use packages must be published through a 2FA-enforced method (e.g., interactive publish with 2FA or staged publishing) [12]. - Persistence: Once a version includes dual-use metadata, all subsequent versions must retain it [8][9]. Staged Publishing Staged publishing allows developers to submit a package to a staging area without immediately making it public [13]. This method is compatible with various credentials, including those that bypass 2FA (for the staging step), but it requires 2FA to be enforced during the final promotion to the live registry [13][12]. This is an effective way to handle CI/CD workflows while still adhering to the 2FA requirement for the final release [1][12].

Scope the OTP result as an incident-specific heuristic.
An npm OTP prompt shows that the registry issued an OTP challenge. It does not establish that content scanning completed before the prompt. If this is a general bisection rule, record the npm CLI version, registry, authentication flow, and response codes used for this incident.

From the rnxORM 2.2.0 release: npm's publish-time content scanner rejected the tarball over SQL-injection payload strings in the README/CHANGELOG (documented as what the ORM rejects), behind a generic 403 identical across OIDC, staged, and interactive publishing. Four wrong diagnoses in a row, one package rename, then a probe-package tell and an EOTP-vs-403 bisection oracle found it in minutes. Gate: defang shipped docs; bisect generic rejections instead of theorizing.
