Description OSIDB Bzimport 2026-10-01 23:09:31 UTC 
A NULL pointer dereference in mod_xml2enc in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an untrusted backend server to cause a denial of service via a proxied response with a charset whose conversion partially succeeds then fails.

Users are recommended to upgrade to version 2.4.69, which fixes this issue.
