CVE-2026-53531 ratex-parser has unbounded parser recursion that leads to stack overflow (process abort)

RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, RaTeX’s recursive-descent parser recurses one or more native stack frame per nesting level at , \left, \sqrt, ^, etc, with no maximum depth limit. A short, 10 KB input of nested groups overflows the 8 MB...

CVE-2026-53530 ratex-parser panics on `\verb` with a multibyte delimiter (UTF-8 byte-boundary slice)

RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, the public parser entrypoint ratexparser::parse&str panics on the 9-byte input \verbéxé i.e. \verb followed by the non-ASCII delimiter é. When handling a \verb command, the parser slices the verbatim...

CVE-2026-53530

RaTeX (a KaTeX-compatible math rendering engine in Rust) is vulnerable to a denial of service in ratex-parser prior to version 0.1.11 . The parser slices the \verb argument using byte indices (arg[1..arg.len() - 1] at parser.rs:910); when the delimiter is a multibyte UTF-8 character (e.g. é), the...

ratex-parser has unbounded parser recursion that leads to stack overflow (process abort)

Summary RaTeX’s recursive-descent parser recurses one or more native stack frame per nesting level at , \left, \sqrt, ^, etc, with no maximum depth limit. A short, 10 KB input of nested groups overflows the 8 MB main-thread stack and aborts the process. With panic = "abort" Cargo.toml:48, and...
