Las especificaciones p\u00fablicas anuncian String.t() como un argumento v\u00e1lido, por lo que pasar una cadena es un uso documentado, y los puntos de entrada de nivel superior, como Guardian.Plug.current_token(conn, key: key), pasan la clave proporcionada por el llamador directamente a estas funciones.\n\nString.to_atom/1 crea un \u00e1tomo completamente nuevo para cada binario no visto anteriormente, los \u00e1tomos nunca son recolectados por el recolector de basura, y la tabla de \u00e1tomos de BEAM est\u00e1 fijada en aproximadamente 1.048.576 entradas por defecto. Una aplicaci\u00f3n que enruta datos influenciados por el atacante (un identificador de inquilino, encabezado u otra entrada de solicitud) en una clave de Guardian, por lo tanto, acu\u00f1a un \u00e1tomo permanente por cada valor distinto. Un flujo modesto de entrada variada y no autenticada consume permanentemente la tabla de \u00e1tomos y bloquea el nodo BEAM, derribando todas las aplicaciones que se ejecutan en \u00e9l.\n\nEste problema afecta a guardian: desde 0.1.0 antes de 2.4.1."}], "id": "CVE-2026-54894", "lastModified": "2026-10-23T22:10:00.160", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.5, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "cvssMetricV40": [{"cvssData": {"Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "attackVector": "LOCAL", "availabilityRequirement": "NOT_DEFINED", "baseScore": 6.9, "baseSeverity": "MEDIUM", "confidentialityRequirement": "NOT_DEFINED", "exploitMaturity": "NOT_DEFINED", "integrityRequirement": "NOT_DEFINED", "modifiedAttackComplexity": "NOT_DEFINED", "modifiedAttackRequirements": "NOT_DEFINED", "modifiedAttackVector": "NOT_DEFINED", "modifiedPrivilegesRequired": "NOT_DEFINED", "modifiedSubAvailabilityImpact": "NOT_DEFINED", "modifiedSubConfidentialityImpact": "NOT_DEFINED", "modifiedSubIntegrityImpact": "NOT_DEFINED", "modifiedUserInteraction": "NOT_DEFINED", "modifiedVulnAvailabilityImpact": "NOT_DEFINED", "modifiedVulnConfidentialityImpact": "NOT_DEFINED", "modifiedVulnIntegrityImpact": "NOT_DEFINED", "privilegesRequired": "NONE", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "HIGH", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "NONE", "valueDensity": "NOT_DEFINED", "vectorString": "CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X", "version": "4.0", "vulnAvailabilityImpact": "HIGH", "vulnConfidentialityImpact": "NONE", "vulnIntegrityImpact": "NONE", "vulnerabilityResponseEffort": "NOT_DEFINED"}, "source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "type": "Secondary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2026-54894", "options": [{"exploitation": "poc"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-08-03T17:49:32.217048Z", "version": "2.0.3"}}]}, "published": "2026-08-01T19:16:41.977", "references": [{"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Third Party Advisory"], "url": "https://cna.erlef.org/cves/CVE-2026-54894.html"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Patch"], "url": "https://github.com/ueberauth/guardian/commit/2952657e42e6341a67e6aaad09d8f0b40ae917cb"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Exploit", "Patch", "Vendor Advisory"], "url": "https://github.com/ueberauth/guardian/security/advisories/GHSA-xqch-c77q-rgh5"}, {"source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "tags": ["Third Party Advisory"], "url": "https://osv.dev/vulnerability/EEF-CVE-2026-54894"}, {"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "tags": ["Exploit", "Patch", "Vendor Advisory"], "url": "https://github.com/ueberauth/guardian/security/advisories/GHSA-xqch-c77q-rgh5"}], "sourceIdentifier": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-770"}], "source": "6b3ad84c-e1a6-4bf7-a703-f496b71e49db", "type": "Secondary"}]}
