Description

This security bulletin contains information about 1 vulnerability.

1) Inefficient regular expression complexity (CVE-ID: CVE-2026-59893)

CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to inefficient regular expression complexity in the dollar-quoted SQL literal lexer and multiline comment patterns when parsing user-supplied SQL text. A remote attacker can send specially crafted SQL input with unmatched dollar-quote delimiters or unterminated comment openers to cause a denial of service.

A single crafted request carrying SQL text is sufficient to trigger sustained CPU exhaustion.

Remediation

Install update from vendor's website.
