OpenSSF/OSV advisory MAL-2026-6509 confirms this npm version as malicious. Package is published as @merceas/anchor but its README, homepage (https://github.com/coral-xyz/anchor\#readme), repository, and source are a verbatim copy of @coral-xyz/anchor — a typosquat/impersonation of the legitimate Solana Anchor SDK. The package.json overrides the standard \`cross-fetch\` dependency with an npm alias to a fork under the same scope: \`"cross-fetch": "npm:@merceas/cross-fetch@3.1.9"\`... ## 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 @merceas/anchor@0.32.3. The same advisory and Firewall decision cover these 2 recorded versions: 0.32.1, 0.32.3. - Avoid installing @merceas/anchor@0.32.3. 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% Package is published as @merceas/anchor but its README, homepage (https://github.com/coral-xyz/anchor\#readme), repository, and source are a verbatim copy of @coral-xyz/anchor — a typosquat/impersonation of the legitimate Solana Anchor SDK. The package.json overrides the standard \`cross-fetch\` dependency with an npm alias to a fork under the same scope: \`"cross-fetch": "npm:@merceas/cross-fetch@3.1.9"\`. Installing this package silently pulls @merceas/cross-fetch into the dependency tree, routing every HTTP call made through the SDK (including dist/cjs/utils/registry.js's \`https://api.apr.dev/api/v0/program/\/latest?limit=\\` call, and any fetches consumers make via the SDK's transport) through code controlled by the same actor that published this typosquat. The cross-fetch substitution is the attack mechanism: the malicious payload is in the transitive package the installer is forced to pull, not in this tarball. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublishOnly - **Dependencies:** 13 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 28 - **Published dependency-graph edges:** 13 ### Published dependency entries - @coral-xyz/anchor-errors ^0.31.1 (Dependency) - @coral-xyz/borsh ^0.31.1 (Dependency) - @noble/hashes ^1.3.1 (Dependency) - @solana/web3.js ^1.69.0 (Dependency) - bn.js ^5.1.2 (Dependency) - bs58 ^4.0.1 (Dependency) - buffer-layout ^1.2.2 (Dependency) - camelcase ^6.3.0 (Dependency) - cross-fetch npm:@merceas/cross-fetch@3.1.9 (Dependency) - eventemitter3 ^4.0.7 (Dependency) - pako ^2.0.3 (Dependency) - superstruct ^0.15.4 (Dependency) - toml ^3.0.0 (Dependency) ## Package metadata - **Package:** @merceas/anchor - **Ecosystem:** npm - **Version:** 0.32.3 - **License:** (MIT OR Apache-2.0) - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 0.32.3 - **Appeal under review:** No - **Description:** Anchor client - **Maintainers:** merceas - **Runtime engines:** node: \>=17 - **Artifact files:** 487 - **Artifact unpacked size:** 1,832,224 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]()
