What happened and what to do
The advisory published on oss-sec on October 1, 2026 reports CVE-2026-79768, a path-equivalence flaw in Apache HTTP Server’s mod_userdir module. The vulnerability may disclose information when UserDir uses an absolute path without a wildcard; the described case involves the “/./” segment. Versions 2.4.0 through 2.4.68 are affected, and the stated severity is low.
A company can inventory Apache servers and their UserDir configurations, identify installations in the affected range, and check whether they use the described combination. It can also test path behavior, record findings, and track applicable update guidance before changing production configuration.
