CVE-2026-28469
OpenClaw versions prior to 2026.2.14 contain a webhook routing vulnerability in the Google Chat monitor component that allows cross-account policy context misrouting when multiple webhook targets share the same HTTP path. Attackers can exploit first-match request verification semantics to process inbound webhook events under incorrect account contexts, bypassing intended allowlists and session policies.
CVSS
- Versión: 4.0

- Puntuación base: 8.2
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.51%
- Percentil entre todas las CVEs puntuadas: 42
- Fecha de la puntuación: 5/10/2026
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).
