Cache Flooding in TYPO3 Frontend

Links with a valid cHash argument lead to newly generated page cache entries. Because the cHash is not bound to a specific page, attackers could use valid cHash arguments for multiple pages, leading to additional useless page cache entries. Depending on the number of pages in the system and the...
