High (7.5) in apache tiles. No vendor fix: the product was unsupported when the CVE was assigned. EPSS 1.4% chance of exploitation in the next 30 days.
The value set as the DefaultLocaleResolver.LOCALE_KEY attribute on the session was not validated while resolving XML definition files, leading to possible path traversal and eventually SSRF/XXE when passing user-controlled data to this key. Passing user-controlled data to this key may be relatively common, as it was also used like that to set the language in the 'tiles-test' application shipped with Tiles.
This issue affects Apache Tiles from version 2 onwards.
NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
