CVE-2026-105295
GitAhead 2.5.0 through 2.7.1 contains an insecure update mechanism that installs downloaded updates without integrity or signature verification and permanently ignores TLS errors after one SSL error dialog. Network attackers presenting an invalid certificate once can intercept later automatic update checks, offer a fake version, and execute code as the user upon installation.
CVSS
- Versión: 4.0
- Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/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
- Puntuación base: 7.7
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.13%
- Percentil entre todas las CVEs puntuadas: 2
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1195.002Compromise Software Supply Chaininitial access90 % - Impacto secundario
T1059Command and Scripting Interpreterexecution85 %
UI:R + necesidad de interacción inicial (aceptar diálogo SSL) → T1203. Mecanismo de actualización insegura con verificación de integridad ausente → T1195.002 (cadena de suministro, componente comprometido). Ejecución de código como usuario en la instalación → T1059.
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.
