{"apiVersion":"1.0","identifier":"CVE-2026-53530","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.","publishedAt":"2026-08-21T22:16:39","lastModifiedAt":"2026-08-24T20:16:48","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53530","cvssScore":8.7,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00253,"riskScore":0.89,"affectedProduct":"RaTeX","affectedVersions":"<0.1.11","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53530","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53530","en":"https://www.redsauce.net/en/cves/CVE-2026-53530","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53530","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53530","de":"https://www.redsauce.net/de/cves/CVE-2026-53530","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53530","el":"https://www.redsauce.net/el/cves/CVE-2026-53530"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53530"}}
