Because Athena and Trino do not treat backslashes as escape characters inside string literals, attacker-supplied input such as a single quote followed by SQL syntax causes the parser to terminate the string literal prematurely, enabling data exfiltration via UNION SELECT, execution of destructive statements, and attacker-controlled CTAS destination and content."}], "datePublic": "2026-08-02T00:00:00.000Z", "problemTypes": [{"descriptions": [{"lang": "en", "cweId": "CWE-89", "description": "Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')", "type": "CWE"}]}], "affected": [{"vendor": "laughingman7743", "product": "PyAthena", "defaultStatus": "affected", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "3.35.3"}]}], "metrics": [{"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV4_0": {"attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "NONE", "userInteraction": "NONE", "vulnConfidentialityImpact": "HIGH", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "CRITICAL", "baseScore": 9.3, "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}}, {"format": "CVSS", "scenarios": [{"lang": "en", "value": "GENERAL"}], "cvssV3_1": {"attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "version": "3.1", "baseSeverity": "CRITICAL", "baseScore": 9.8, "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}}], "references": [{"url": "https://github.com/laughingman7743/PyAthena", "name": "Product Repository", "tags": ["product"]}, {"url": "https://github.com/laughingman7743/PyAthena/security/advisories/GHSA-xwj5-g6cv-4r5c", "name": "GitHub Security Advisory", "tags": ["vendor-advisory"]}, {"url": "https://github.com/pyathena-dev/PyAthena/commit/27901d12245ea722b3b4e211c60e2ade4e7c8efd", "name": "Patch Commit", "tags": ["patch"]}, {"url": "https://www.vulncheck.com/advisories/pyathena-sql-injection-via-defaultparameterformatter-delete-ctas", "tags": ["third-party-advisory"]}], "credits": [{"lang": "en", "value": "Rahul Karne", "type": "reporter"}], "source": {"discovery": "EXTERNAL"}, "x_generator": {"engine": "vulncheck-endgame"}}}}
