{"apiVersion":"1.0","identifier":"CVE-2026-53531","description":"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 main-thread stack and aborts the process. With `panic = -abort-` (`Cargo.toml:48`), and because a Rust stack overflow is always a fatal `SIGABRT` regardless of panic strategy this is an unrecoverable, whole-process denial of service reachable from a single untrusted LaTeX string. Version 0.1.11 fixes the issue.","publishedAt":"2026-08-21T22:16:39","lastModifiedAt":"2026-08-25T17:17:29","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53531","cvssScore":6.9,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/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":0.00257,"riskScore":0.71,"affectedProduct":"RaTeX","affectedVersions":"<0.1.11","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53531","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53531","en":"https://www.redsauce.net/en/cves/CVE-2026-53531","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53531","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53531","de":"https://www.redsauce.net/de/cves/CVE-2026-53531","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53531","el":"https://www.redsauce.net/el/cves/CVE-2026-53531"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53531"}}
