CVE ID :CVE-2026-53530
Published : Aug. 21, 2026, 10:16 p.m. | 2 hours, 17 minutes ago
Description :RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, the public parser entrypoint `ratex_parser::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 argument with byte indices (`arg[1..arg.len() – 1]`); if the delimiter character is multibyte UTF-8, index `1` lands inside that character and Rust panics with *“byte index 1 is not a char boundary”*. Because RaTeX’s release profile sets `panic = “abort”` (`Cargo.toml:48`), the panic aborts the entire process — not just the current request/thread — making this a hard denial of service for any service that renders untrusted LaTeX. Version 0.1.11 fixes the issue.
Severity: 8.7 | HIGH
