CVE-2026-22732

Estado: AnalizadaCrítica (9.1)—

When applications specify HTTP response headers for servlet applications using Spring Security, there is the possibility that the HTTP Headers will not be written. This issue affects Spring Security Servlet applications using lazy (default) writing of HTTP Headers:

: from 5.7.0 through 5.7.21, from 5.8.0 through 5.8.23, from 6.3.0 through 6.3.14, from 6.4.0 through 6.4.14, from 6.5.0 through 6.5.8, from 7.0.0 through 7.0.3.

Vector CVSS AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). El fallo en escribir headers HTTP permite manipular respuestas (T1565.002) e inapropiadamente exponer información sensible (T1552.001).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
