Description OSIDB Bzimport 2026-10-01 23:06:31 UTC 
Deployment of wrong handler vulnerability in Apache HTTP Server allows the target of some internal redirects from CGI programs to also be treated as CGI and executed. The target must already be in a directory enabled for CGI and have no other extension understood by mod_mime.



This issue affects Apache HTTP Server: from 2.4.60 through 2.4.68.
