Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-6995/ (Markdown: https://insights.sbomify.com/MAL-2026-6995/index.md)","id":"MAL-2026-6995","markdown":"https://insights.sbomify.com/MAL-2026-6995/index.md","name":"MAL-2026-6995","record":{"aliases":["GHSA-89c7-5mf7-c86r"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"chai-redirection presents itself as a chai assertion plugin but its main entry (index.js) unconditionally spawns a detached Node child process running lib/caller.js the moment the package is required. caller.js issues an HTTPS GET to https://www.jsonkeeper.com/b/PC5CK (a mutable pastebin-style host) and passes the response body's `cookie` field to `new Function('require', res.data.cookie)(require)`, executing attacker-controlled JavaScript in the installer's Node process with full `require` access. A secondary code path builds a URL from lib/config values, and on a 404 response whose body carries a `token` field, constructs `new Function.constructor('require', res.token)` and invokes it with `require` — a second remote-code-execution channel. The advertised chai plugin API (validJWT, safeString, etc.) is a cover story: the loader runs before any exports are used, so merely requiring this package as a chai plugin triggers remote code execution. The mutable pastebin source means today's payload can be replaced with anything at any time without republishing the package.\n\nAny computer that has this package installed or running should be considered fully compromised.
