Severity: High · CVSS 7.8CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H
Published: Jul 10, 2025, 12:00:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 1.30% · Oct 25, 2026

A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.
