Description OSIDB Bzimport 2026-05-04 15:01:48 UTC
A NULL pointer dereference in the mod_authn_socache in Apache HTTP Server 2.4.66 and earlier allows an unauthenticated remote user to crash a child process in a caching forward proxy configuration.

Users are recommended to upgrade to version 2.4.67, which fixes this issue.
