How severe is CVE-2026-23868?

CVE-2026-23868 has a CVSS v3 base score of 7.0, rated important. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

What does CVE-2026-23868 affect?

Published advisories record a fix for giflib (Amazon), giflib-debuginfo (Amazon), giflib-debugsource (Amazon), giflib-devel (Amazon), and 22 more. Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.
