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...

CVE-2026-49293 CPU exhaustion via O(n^2) BigInt construction on radix-prefixed integer literals

js-toml is a TOML parser for JavaScript, fully compliant with the TOML 1.0.0 Spec. Versions up to and including 1.1.0 parse hexadecimal / octal / binary integer literals via a hand-written parseBigInt loop that multiplies a BigInt accumulator by the radix once per input digit. Each iteration...

PT-2026-51007

Name of the Vulnerable Software and Affected Versions js-toml versions prior to 1.1.1 Description The software contains a quadratic time complexity issue during the parsing of hexadecimal, octal, and binary integer literals. This occurs because the parseBigInt function uses a loop that performs a...

Unity Linux 20.1070e Security Update: mariadb (UTSA-2026-021663)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-021663 advisory. MariaDB through 10.5.9 allows attackers to trigger a convertconsttoint use-after-free when the BIGINT data type is used. Tenable has extracted the preceding...

Astra Linux – Vulnerability in Mariadb 10.3

📄 V8 BigInt String Conversion Stress Test Conceptual Sandbox

This is a V8 Sandbox Escape vulnerability in BigInt::Allocate where buffers are shuffled outside the sandbox. The vulnerability allows for writes outside the boundaries of the allocated buffer within the sandbox outbound write by manipulating data during the MultiplyFFT process...

📄 V8 Sandbox Bypass: BigInt Division Memory Corruption

This is a variant of crbug.com/474041332. The issue there was that MultiplyFFT, an optimized version of integer multiplication for very large inputs, is not robust against concurrent modification of its input buffers, but was called from ProcessorImpl::FromStringLarge with a temporary buffer insi...

📄 V8 StringToBigInt Memory Corruption Sandbox Bypass

V8 suffers from a sandbox bypass vulnerability due to memory corruption during StringToBigInt conversion. The function v8::internal::StringToBigInt is used by V8 when converting a string to a BigInt e.g. via BigInt“1337”. It first parses the string into individual digitt’s in the...

CVE-2026-4599

Versions of the package jsrsasign from 7.0.0 and before 11.1.1 are vulnerable to Incomplete Comparison with Missing Factors via the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions in src/crypto-1.1.js; an attacker can recover the private key by exploiting the incorrect...

jsrsasign 安全漏洞

jsrsasign is a signature verification library developed by Kenji Urushima. Versions of jsrsasign from 7.0.0 to 11.1.1 contained security vulnerabilities. These vulnerabilities stemmed from incomplete comparisons in the getRandomBigIntegerZeroToMax and getRandomBigIntegerMinToMax functions located...
