CVE-2025-47151
A type confusion vulnerability exists in the lasso_node_impl_init_from_xml functionality of Entr'ouvert Lasso 2.5.1 and 2.8.2. A specially crafted SAML response can lead to an arbitrary code execution. An attacker can send a malformed SAML response to trigger this vulnerability.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.05%
- Percentil entre todas las CVEs puntuadas: 63
- Fecha de la puntuación: 5/10/2026
