From 1.3.1.1 to before 2.2.7.4, a signed length truncation bug causes an out-of-bounds read in the default Markdown parse path. Inputs larger than INT_MAX are truncated to a signed int before entering the native parser, allowing the parser to read past the end of the supplied buffer and crash the process. This vulnerability is fixed in 2.2.7.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9},"cwes":["CWE-125"],"references":["https://github.com/davidfstr/rdiscount/security/advisories/GHSA-6r34-94wq-jhrc"],"products":["dafoster:rdiscount"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-35201","score":0.00275,"percentile":0.19893,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6r34-94wq-jhrc","url":"https://osv.dev/vulnerability/GHSA-6r34-94wq-jhrc","summary":"rdiscount has an Out-of-bounds Read","modified":"2026-05-13T16:35:44.190293Z","packages":[{"ecosystem":"RubyGems","name":"rdiscount","purl":"pkg:gem/rdiscount","ranges":[">=1.3.1.1 <2.2.7.4"],"fixed":["2.2.7.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
