Date: 2026-05
Affected: composer/tpwd/ke_search, composer/tpwd/ke_search, composer/tpwd/ke_search
Attack vector: other
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2026-46722
CWE: CWE-611

In TYPO3 faceted fulltext search (`ke_search`), 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. This has been patched in versions 7.0.1, 6.6.1, 5.6.2 and 4.6.7.
