CVE-2026-56095 Insecure Deserialization in extension "Apache Solr for TYPO3 - Enterprise Search" (solr)

The extension's indexer passed every field value returned by content object rendering through PHP's unserialize function when transferring multi-value data for the SOLRCLASSIFICATION, SOLRMULTIVALUE and SOLRRELATION content object types, rather than a safe format. If user-generated content saved ...
