sqlparse is a non-validating SQL parser module for Python. Prior to 0.6.0, sqlparse/filters/output.py fails to escape existing backslashes before quotes in sqlparse.format output_format='python' and output_format='php' and the corresponding sqlformat -l modes, allowing crafted SQL to terminate the generated string and inject Python or PHP code when a downstream consumer executes or imports the generated source. This issue is fixed in version 0.6.0.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21690-1 advisory.

    - CVE-2026-54284: high algorithm complexity when parsing SQL payloads with hundreds of nesting levels can     lead to denial       of service via excessive resource consumption (bsc#1275459).
    - CVE-2026-59893: quadratic complexity when processing unmatched dollar-quoted literal and multiline-     comment delimiters       can lead to denial of service (bsc#1275461).
    - CVE-2026-59894: improper backlash escaping allows for injection of Python or PHP code via a crafted SQL     input       (bsc#1275460).
    - CVE-2026-71491: quadratic complexity in `group_comments` when processing comment-only statements can     lead to denial       of services (bsc#1275466).
    - Incomplete GHSA-27jp-wm6q-gp25 patch (bsc#1268597).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3762-1 advisory.

    - CVE-2026-54284: TokenList.__init__ materializes O(subtree) value per group, causing CPU DoS before     depth/token caps       trigger (bsc#1275459).
    - CVE-2026-59893: Inefficient Regex Handling of Dollar-Quoted SQL Literals Leads to ReDoS (bsc#1275461).
    - CVE-2026-59894: Generated Python and PHP snippets allow SQL string breakout through unescaped     backslashes       (bsc#1275460).
    - CVE-2026-71491: quadratic O(n2) DoS in group_comments (bsc#1275466).

Tenable has extracted the preceding description block directly from the SUSE security advisory.
