duplicated content, missing redirect "By-passing protection of Phar Stream Wrapper Interceptor"
The same article is visible under 2 links https://typo3.org/article/by-passing-protection-of-phar-stream-wrapper-interceptor-1/ https://typo3.org/article/by-passing-protection-of-phar-stream-wrapper-interceptor/
and also indexed by google twice.
AFAIK the link with -1 in url is the correct (later version).
