CVE-2024-36400

Date: June 4, 2024

nano-id is a unique string ID generator for Rust. Affected versions of the nano-id crate incorrectly generated IDs using a reduced character set in the "nano_id::base62" and "nano_id::base58" functions. Specifically, the "base62" function used a character set of 32 symbols instead of the intended 62 symbols, and the "base58" function used a character set of 16 symbols instead of the intended 58 symbols. Additionally, the "nano_id::gen" macro is also affected when a custom character set that is not a power of 2 in size is specified. It should be noted that "nano_id::base64" is not affected by this vulnerability. This can result in a significant reduction in entropy, making the generated IDs predictable and vulnerable to brute-force attacks when the IDs are used in security-sensitive contexts such as session tokens or unique identifiers. The vulnerability is fixed in 0.4.0.
