CVE-2026-79771 is fixed in ruby-nokogiri on 1 platform by DEBIAN-CVE-2026-79771 (version 1.19.3+dfsg-1), released August 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
Nokogiri versions before 1.19.3 contain a memory leak in the XSLT Stylesheet transform method when processing Ruby strings containing null bytes. Attackers can exploit this by passing attacker-controlled input with null bytes to transform parameters, causing heap allocations to leak and enabling denial of service against long-running processes.
