Improper Verification of Cryptographic Signature Affecting nano-id package, versions <0.4.0
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2024-36400 (opens in a new tab)How to fix?
Upgrade nano-id to version 0.4.0 or higher.
Overview
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature through the nano_id::base62 and nano_id::base58 functions. An attacker can predict generated IDs and potentially perform brute-force attacks by exploiting the reduced entropy of these IDs.
Note
nano_id::base64 is not affected by this vulnerability.
