CVE-2025-71382 is fixed in mupdf on 1 platform by DEBIAN-CVE-2025-71382 (version 1.27.0+ds1-2), released June 27, 2026. It is not reported as exploited. Patch Radar priority: Routine.
MuPDF before 1.27.0-rc1 contains an uncontrolled recursion vulnerability in the EPUB CSS rendering engine that allows remote attackers to cause a denial of service by supplying a maliciously crafted EPUB file with deeply nested HTML elements and inline CSS styles. The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, exhausting the process stack and causing a crash in any application using MuPDF for EPUB rendering.
