A high-severity denial of service vulnerability (CVE-2026-67213) was discovered in nanoid versions before 5.1.6 and 3.3.18, where the `customAlphabet` function could enter an infinite loop during random ID generation. The fix upgrades the transitive nanoid dependency from 3.3.16 to 3.3.18 using pnpm overrides, ensuring the vulnerable code path is eliminated from the entire dependency tree including PostCSS.
CVE-2026-67213 is a high-severity Denial of Service vulnerability in the popular nanoid package, where a flaw in the custom alphabet ID generation logic could trigger an infinite loop, hanging the process indefinitely. The fix upgrades nanoid from 3.3.16 to 3.3.18 (and pins the 5.x branch to 5.1.6), patching the loop condition so that all valid alphabet inputs terminate correctly. Any Node.js or Bun application using nanoid's `customAlphabet` function with user-influenced input is potentially af
A high-severity infinite loop vulnerability (CVE-2026-67213) was discovered in nanoid versions before 5.1.6 and 3.3.17, affecting the custom alphabet generation feature. When processing certain malformed alphabet configurations, nanoid would enter an infinite loop, causing a complete denial of service. This vulnerability was fixed by upgrading from nanoid 3.3.16 to 3.3.17 and implementing dependency overrides to ensure the patched version is used throughout the dependency tree.
A high-severity infinite loop vulnerability (CVE-2026-67213) was discovered in the nanoid package's `customAlphabet` function, affecting versions before 5.1.6. The concord-frontend application depended on nanoid 6.0.1, which contained this flaw. The fix downgrades to nanoid 3.3.17, a patched version that eliminates the infinite loop condition triggered by crafted input to custom alphabet ID generation.
