CVE-2026-85730

Описание

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 resets the cursor to the beginning of the string instead of leaving the structure scan. The parser then hangs indefinitely and can consume a service's processing capacity when an application parses attacker-controlled TOML. This issue is fixed in version 1.7.1.

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. Successful exploitation leads to a Denial of Service (DoS), causing the parser to hang indefinitely and consume service processing capacity.
