https://notcve.org/view.php?id=CVE-2021-3827
18 Jan 2022 — A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity. Se ha encontrado un fallo en keycloak, en el que el flujo de vinculación ECP por defecto permite omitir otros flujos de autenticación.

23 Dec 2021 — load_cache in GEGL before 0.4.34 allows shell expansion when a pathname in a constructed command line is not escaped or filtered. This is caused by use of the system library function for execution of the ImageMagick convert fallback in magick-load. NOTE: GEGL releases before 0.4.34 are used in GIMP releases before 2.10.30; however, this does not imply that GIMP builds enable the vulnerable feature. load_cache en GEGL antes de la versión 0.4.34 permite la expansión del shell cuando un nombre de ruta en una l... • https://gitlab.gnome.org/GNOME/gegl/-/blob/master/docs/NEWS.adoc • CWE-20: Improper Input Validation •
