AnalysisAI
Filter bypass in PHP-FTS (olivier-ls/php-fts) through version 1.1.3 allows an authenticated remote attacker to defeat document-scoping filters used by consuming applications for ownership or multi-tenant isolation, exposing search results the application intended to hide. The flaw resides in SearchEngine::matchesSingleFilter in src/SearchEngine.php, where filter values were compared with loose == and non-strict in_array(); because PHP treats any non-empty string as equal to boolean true, a filter value of true matched every document with a non-empty value in that field, and the string '42' matched the integer 42, enabling retrieval of other users' or tenants' records. …
