HighCVSS 7.7

Exploitation Probability (EPSS)

Low risk
0.25%

16th percentile - higher than 16% of all known CVEs

Summary

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.

Risk Assessment

An attacker can exploit PHP Object Injection to execute arbitrary code or manipulate objects, potentially leading to full system compromise or data breach.

Recommendation

Use a safe serialization format (e.g., JSON) instead of unserialize() for multi-value data in the indexer to prevent PHP object injection.
