If an untrusted user has admin rights to a tenant instance, they will be able to install a plug-in that can access information from other tenants\n\n### Revived after 0.8.7\nAfter patch in 0.8.7 this is not fixed completely.\n\nHere are steps to reproduce:\n1. Publish to NPM plugin that was not approved by admin (in case of saltcorn.com) by @glutamate. I've just published this one: https://www.npmjs.com/package/saltcorn-qrcode\n2. Publish somewhere plugin store that includes plugin from previous step: https://gist.github.com/pyhedgehog/f1fd7cb13f4d0a7ccf6a965748d19bd2\n3. Add plugin store link to tenant store.\n4. Install plugin.\n5. Use it in tenant: https://bot20230704.saltcorn.com/view/testqr_show/1\n\nHere are logic:\nUnsafe plugins checked against this list:\nhttps://github.com/saltcorn/saltcorn/blob/99fe277e497fd193bb070acd8c663aa254a9907c/packages/server/load_plugins.js#L191\nBut it's under control of tenant admin, not server admin.\nProposed login:\n```javascript\nconst safes = getRootState().getConfig(\"available_plugins\",[]).filter(p=>!p.unsafe).map(p=>p.location);\n```","published":"2023-07-27T19:28:02Z","modified":"2026-02-03T03:12:28.153627Z","cvss":{"score":8.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@saltcorn/cli","fixedVersion":"0.8.8-beta.2"}],"fix":{"url":"https://github.com/saltcorn/saltcorn/pull/1973","label":"saltcorn/saltcorn#1973"},"references":[{"type":"WEB","url":"https://github.com/saltcorn/saltcorn/security/advisories/GHSA-wxf3-4fvj-vqqx"},{"type":"WEB","url":"https://github.com/saltcorn/saltcorn/pull/1973"},{"type":"WEB","url":"https://github.com/saltcorn/saltcorn/commit/0f32a51277a635c814a634bda9b6d358fb8c04ab"},{"type":"PACKAGE","url":"https://github.com/saltcorn/saltcorn"},{"type":"WEB","url":"https://github.com/saltcorn/saltcorn/blob/99fe277e497fd193bb070acd8c663aa254a9907c/packages/server/load_plugins.js#L191"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-02-03T03:12:28.153627Z"}}
