{"schema":"threatline.record/2","record":{"id":"CVE-2026-49206","aliases":["GHSA-v83v-8j5q-6553"],"summary":"rapidcsv: Integer overflow in iterator arithmetic causes out-of-bounds access","details":"rapidcsv is a C++ CSV parser library. Prior to 8.99, RemoveColumn, InsertColumn, RemoveRow, InsertRow, and GetColumnNames converted size_t indexes to int before adding them to std::vector iterators. On 64-bit systems, in a CSV matrix dimension containing more than 2^31 elements, an index above INT_MAX could wrap to a negative iterator offset and point before the start of the vector, causing undefined behavior, heap memory corruption, or a crash. Triggering the issue requires an extremely large in-memory document, requiring tens of gigabytes of memory at minimum, so typical CSV documents are not practically affected. This issue is fixed in version 8.99.","categories":["Unclassified"],"product":"rapidcsv","vendor":"d99kris","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-49206","source_modified_at":"2026-10-15T19:08:15.368Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"rapidcsv","vendor":"d99kris","versions":[{"version":"< 8.99","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.9,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00157,"percentile":0.04437,"score_date":"2026-10-23"},"published_at":"2026-10-14T15:44:43.286Z","modified_at":"2026-10-15T19:08:15.368Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-49206","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T19:08:15.368Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-49206","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/d99kris/rapidcsv/security/advisories/GHSA-v83v-8j5q-6553","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/d99kris/rapidcsv/issues/220","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/d99kris/rapidcsv/commit/68f57cc6c83d5e0992904398822453489d8dfac1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/d99kris/rapidcsv/releases/tag/v8.99","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T19:08:02.867667Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T19:08:15.368Z","content_hash":"d9fa516f4fec60ccbfd303b1af1c1544be52c455dbddee5283ee43a51c2c7e0e"}}
