SUSE CVE-2026-63376

toml-node is a TOML parser for Node.js and the browser. Prior to 4.1.2, toml.parse in lib/compiler.js can be tricked by a table path such as a.b.y.proto.proto, allowing traversal from a scalar value into Number.prototype and Object.prototype. The currentPath tracking value uses both arrays and...

CVE-2026-85730

smol-toml is a small, fast, and correct TOML parser and serializer. Prior to 1.7.1, parse can enter an infinite loop when a value inside an array or inline table is followed by a comment with no trailing newline. In src/util.ts, skipUntil calls indexOfNewline, receives -1 at the end of input, and...

CVE-2026-85730

A flaw was found in smol-toml, a TOML parser and serializer. A remote attacker could exploit an infinite loop in the parse function by providing a specially crafted TOML document. This occurs when a value within an array or inline table is followed by a comment without a trailing newline...

CVE-2026-85730 smol-toml: Denial of Service via malformed TOML documents

smol-toml is a small, fast, and correct TOML parser and serializer. Prior to 1.7.1, parse can enter an infinite loop when a value inside an array or inline table is followed by a comment with no trailing newline. In src/util.ts, skipUntil calls indexOfNewline, receives -1 at the end of input, and...

CVE-2026-85730

smol-toml , a lightweight TOML parser and serializer for JavaScript/TypeScript, is vulnerable to a Denial of Service via malformed TOML documents prior to version 1.7.1 . The root cause lies in src/util.ts, where skipUntil() calls indexOfNewline() and receives -1 at end-of-input, causing the curs...

CVE-2026-77465 toml-node: Uncontrolled Recursion

toml-node is a TOML parser for Node.js and the browser. Prior to 4.2.0, toml.parse uses a Peggy 5.1.0 generated recursive-descent parser in lib/parser.js whose peg$parsevalue, peg$parsearray, and peg$parseinlinetableentry functions recurse through nested arrays and inline tables without a depth...

CVE-2026-63376 toml-node: Prototype Pollution Leads to `Object.prototype` Corruption via `__proto__` Key-Path Desynchronization

toml-node is a TOML parser for Node.js and the browser. Prior to 4.1.2, toml.parse in lib/compiler.js can be tricked by a table path such as a.b.y.proto.proto, allowing traversal from a scalar value into Number.prototype and Object.prototype. The currentPath tracking value uses both arrays and...

CVE-2026-63376

toml-node , a TOML parser for Node.js and the browser, is affected by a prototype pollution vulnerability in toml.parse() (lib/compiler.js) prior to version 4.1.2. The root cause is a key-path desynchronization : currentPath tracking uses both arrays and strings, so valueAssignments records a com...

CVE-2026-50029

js-toml is a TOML parser for JavaScript, Prior to version 1.1.2, the interpreter checks whether a key already exists in a parser-built container with if objectkey instead of if key in object. When the prior value is a falsy primitive — false, 0, 0n, 0.0, -0, or "" — the duplicate-key branch is...

CVE-2026-49293

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...

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...
