CVE-2026-63386

js-toml is a TOML parser for JavaScript. Prior to 1.1.3, load does not bound nesting or dotted-key depth in the recursive parser at src/load/parser.ts or the interpreter at src/load/interpreter.ts, so deeply nested arrays, deeply nested inline tables, or long dotted keys can exhaust the V8 call...

CVE-2026-63386 js-toml: Uncontrolled recursion in `load()` causes `RangeError` (stack exhaustion) on deeply nested input

js-toml is a TOML parser for JavaScript. Prior to 1.1.3, load does not bound nesting or dotted-key depth in the recursive parser at src/load/parser.ts or the interpreter at src/load/interpreter.ts, so deeply nested arrays, deeply nested inline tables, or long dotted keys can exhaust the V8 call...

CVE-2026-63386

The js-toml JavaScript TOML parser is vulnerable to a denial of service (DoS) due to uncontrolled recursion in the load() function. In versions prior to 1.1.3 , the recursive parser at src/load/parser.ts and the interpreter at src/load/interpreter.ts fail to bound the nesting depth of arrays, inl...

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-2026-50029

Affects js-toml prior to 1.1.2. The parser uses if (object[key]) to decide duplicates, causing falsy primitives (false, 0, 0n, 0.0, -0, "") to be overwritten by later keys; this yields structural type confusion in load() output (e.g., isAdmin becomes truthy object). MITRE/ATT&CK not specified in ...
