Summary
The additional_tables configuration of the page and tt_content indexers accepts arbitrary table and field names. A backend user with permission to edit indexer configurations can copy sensitive data from internal TYPO3 tables into the search index.
Risk Assessment
A backend user can expose sensitive data from internal TYPO3 tables through the search index, which may be accessible to others. This poses a risk to data confidentiality.
Recommendation
Restrict permissions to edit indexer configurations to trusted administrators. Review search index contents for unexpected data.
Other vulnerabilities in TYPO3
See all- CVE-2026-113459High
In versions running on TYPO3 10 and 11, the configured OpenAI API key is embedded in every backend page so that the editor plugin can contact the OpenAI service directly from the browser. Any authenticated backend user can read the key and use it at the expense of the site operator. This only applies if an API key has been configured.
- CVE-2026-46722Medium
The OOXML parsing of the file indexer does not disable external entity resolution. A crafted xlsx or pptx document placed in an indexed directory can cause local files to be read or outbound HTTP requests to be performed, with the retrieved content being written to the search index.
