CVE-2026-49135

Estado: AplazadaAlta (7.2)—

CodexBar prior to 0.32.0 contains an insecure temporary file handling vulnerability that allows local attackers to access sensitive credentials or tamper with build artifacts by exploiting predictable file paths in the release notarization workflow. Attackers with access to the same host can read the App Store Connect API key written to a fixed path, pre-create files or symbolic links at predictable locations to redirect writes to attacker-controlled destinations, or tamper with notarization archives before submission.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L/PR:L sin UI, con CWE-59 (permisos inseguros) y CWE-377 (archivos temporales predecibles). Acceso local con privilegios a credenciales (App Store Connect API key) y manipulación de artefactos de compilación.

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.
