Your front end and your back end disagree about where one request ends and the next begins. The smuggled prefix slides under the WAF, defeats the rate limiter, and poisons the cache under someone else else URL. How CL-TE and TE-CL desyncs work, and the configuration discipline that closes them.
One curl request to /.git/HEAD hands attackers your full source, every commit ever made, deleted files, and usually a working credential. A decade of research says this mistake is not aging out. Here is the exploit chain — and the three-layer fix.
