Deeper analysis

CVE-2026-27336 is an Improper Control of Filename for Include/Require Statement in PHP Program vulnerability, classified under CWE-98, that enables PHP Local File Inclusion in the Consultor | Consulting, Accounting & Legal Counsel WordPress Theme by AncoraThemes. This flaw affects all versions of the theme from unspecified initial releases through 1.2.4, stemming from inadequate validation of filenames used in PHP include or require statements.
