CVE-2026-1237855.5 MÉD—
——0Fluxbox through 1.3.7 contains an infinite loop vulnerability in Menu::updateMenu() in src/FbTk/Menu.cc that allows attackers to hang the window manager via crafted style geometry values. Attackers can supply a style with an oversized unbounded menu.titleHeight so the column loop never terminates, causing sustained CPU use and denial of service at startup.10hCVE-2026-1232736.5 MÉD28.0%
——8ImageMagick before 7.1.2-35 and 6.9.13-60 contains an infinite loop vulnerability in the SVG decoder because QueueAuthenticPixelCacheNexus in MagickCore/cache.c fails to validate requested region width and height. Attackers can supply a crafted SVG image that repeatedly requests a non-advancing pixel region, consuming CPU and hanging the decoding worker.1dCVE-2026-1109317.5 ALT40.4%
——12A flaw was found in the SAML 1.1 assertion parser of Keycloak, a tool used for identity and access management. The issue occurs when the parser handles a specific element called AuthorityBinding within an authentication statement. Due to an incomplete fix for a previous vulnerability, the parser can enter an infinite loop that consumes all available memory, causing the entire Keycloak service to crash and become unavailable to users.10hCVE-2026-1076027.5 ALT44.5%
——13A flaw was found in the SAML 1.1 XML parsing logic of Keycloak, an open-source identity and access management solution. The issue occurs when the parser encounters unexpected elements within a security token's key information section, causing the processing thread to enter an infinite loop. An unauthenticated remote attacker could exploit this by sending specially crafted requests, leading to 100% CPU usage and a total denial of service that requires a server restart to resolve.10hCVE-2026-33969—7.0%
——2In the NAS Authentication Request message decoding procedure, a missing lower bound check causes an infinite loop, leading to Denial of Service.6hCVE-2026-1223057.7 ALT22.9%
——7Kyverno before 1.19.2 contains a denial of service vulnerability in substituteVariablesIfAny that allows low-privileged users to hang the admission webhook via self-referential variable templates. Attackers can create resources whose annotations re-introduce the embedded policy variable, causing unbounded substitution loops that exhaust CPU and memory and block cluster-wide admission.2d
