What is GHSA-6jqf-mv7m-3q7p?
GHSA-6jqf-mv7m-3q7p is a vulnerability in github.com/filebrowser/filebrowser, published on 13 Nov 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The standard library net/http package dependency used by File Browser improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. I can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.
