Submit #943923: olivier-ls PHP-FTS 0.1 Incorrect Comparisoninfo

Titleolivier-ls PHP-FTS 0.1 Incorrect Comparison
DescriptionPHP-FTS (ols/php-fts) before an unreleased fix uses loose comparison in `SearchEngine::matchesSingleFilter()` for the `=`, `!=`, `in`, `not in`, `contains`, and `not contains` filter operators (PHP `==`/`!=` and `in_array(..., strict: false)`). This allows PHP type juggling: a non-empty string field value compares equal to boolean `true`, so an attacker-supplied filter value such as `[true]` matches every document with a non-empty string field, bypassing filters that applications use for tenant or ownership isolation and disclosing other tenants'/users' indexed documents. Reproduction: https://github.com/sumo166/CVE-apply/blob/main/olivier-ls/php-fts/SearchEngine%20matchesSingleFilter%20Loose%20Comparison%20Filter%20Bypass%20(CWE-697)_cve.md
