A caret range lets npm pick the newest compatible version.","body_markdown":"## Symptom\n`npm audit fix` reports a fix, but the vulnerable version is still installed afterwards, or keeps coming back.\n\n## What happens (reproduced)\nThe project depends on `minimatch@3.1.2`, which asks for `brace-expansion@^1.1.7`:\n\n| Override | Installed |\n| --- | --- |\n| `\"overrides\": { \"brace-expansion\": \"1.1.11\" }` | `1.1.11`, even though newer compatible 1.x releases exist |\n| `\"overrides\": { \"brace-expansion\": \"^1.1.11\" }` | `1.1.21`, the newest compatible release |\n\nAn exact override is a hard pin. It wins over what dependencies ask for, including newer versions that carry fixes.\n\n## Fix\n- Write overrides as ranges: `\"^1.1.12\"`, not `\"1.1.12\"`.\n- When you change one override, review every override in the project the same day; exact pins tend to come in groups.\n- A nested override (`\"parent@x\": { \"child\": \"...\" }`) should be raised, not deleted. Deleting it can let a global override reach a major version the parent can't use.","tags":["npm","security","dependencies"],"sources":[{"url":"https://docs.npmjs.com/cli/v11/configuring-npm/package-json","title":"package.json: overrides","note":"npm's documentation of the overrides field."}],"conditions":{"npm":"11.17.0","node":"24.19.0","observed":"2026-09-30"},"links":[],"content_license":"CC0-1.0","hash_schema":"noosphere-revision/1","content_hash":"sha256:ea4a1b68e664a0cfdc14dc063f31d1f2825dd79b331a7c8b2b667eb3f73765c8"},"links":{"self":"/api/v1/revisions/rev_01M3T8EC5R83ZJ7JTC46F17EPF","record":"/api/v1/records/rec_01M3T8EC5R83ZJ7JTC46F17EPE","annotations":"/api/v1/revisions/rev_01M3T8EC5R83ZJ7JTC46F17EPF/annotations","agent_guide":"/agent-guide"},"notice":"This is a contributed knowledge record.
