    CVE-2026-65321 (GCVE-0-2026-65321)

    Vulnerability from nvd – Published: 2026-08-02 14:56 – Updated: 2026-08-03 11:03

    Title
    PyAthena 3.35.4 SQL Injection via DefaultParameterFormatter DELETE/CTAS
    Summary
    PyAthena prior to 3.35.4 contains a sql injection vulnerability that allows unauthenticated attackers to inject arbitrary SQL by exploiting improper quote-escaping in DefaultParameterFormatter.format(), which routes DELETE and CTAS statements to the _escape_hive function that backslash-escapes single quotes rather than doubling them. 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.
