A remote attacker can supply JavaScript input that triggers an exception and reaches jslPrintTokenLineMarker(), which passes the address of a 4-byte int column variable to jsvGetLineAndCol() as a size_t pointer. jsvGetLineAndCol() performs an 8-byte write through the mismatched pointer, overwriting adjacent stack memory.","categories":["Unclassified"],"product":"n/a","vendor":"n/a","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-88388","source_modified_at":"2026-09-25T15:14:38.255Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"n/a","vendor":"n/a","versions":[{"version":"n/a","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00318,"percentile":0.23578,"score_date":"2026-10-23"},"published_at":"2026-09-24T00:00:00.000Z","modified_at":"2026-09-25T15:14:38.255Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-88388","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T15:14:38.255Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88388","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/espruino/Espruino/commit/ecd7d43e084ba9aafa8245609347fe0f4383b38c"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-25T15:14:04.581717Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-25T15:14:38.255Z","content_hash":"4deaf0ede9b59e5e7acb4d8dac25045aa359ee6e516b0fc6b9c79f31582a7fa7"}}
