CVE-2026-56095

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

CVSS 4.0 7.7 HIGHCheck source for fixed versionsKEV status unknown

Original advisory

cve-program · CVE-2026-56095

Published

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 SOLR_CLASSIFICATION, SOLR_MULTIVALUE and SOLR_RELATION content object types, rather than a safe format. If user-generated content saved in the TYPO3 database can reach an indexed field, this exposes a PHP Object Injection surface.
