CVE-2026-49293

CVE-2026-49293 affects js-toml up to v1.1.0. The parsing of hexadecimal/octal/binary integer literals uses a hand-written parseBigInt loop that multiplies the BigInt accumulator by the radix for every digit, yielding an O(n^2) time complexity in the length of the literal. A single TOML document c...

EUVD-2025-34778

A vulnerability exists in the QuickJS engine's BigInt string parsing logic jsbigintfromstring when attempting to create a BigInt from a string with an excessively large number of digits. The function calculates the necessary number of bits nbits required to store the BigInt using the formula:...

CVE-2025-62496

The CVE refers to QuickJS: BigInt parsing in js_bigint_from_string. When converting a decimal string with an extremely large number of digits, the code computes n_bits as (n_digits × 27 + 7) / 8. For very large inputs (e.g., tens of millions of digits), this intermediate value overflows a 32-bit ...
