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.

TikiWiki contains a flaw that may allow a malicious user to execute
arbitrary PHP code. The issue is triggered due to the jhot.php script
not correctly verifying uploaded files. It is possible that the flaw
may allow arbitrary PHP code execution by uploading a malicious PHP
script resulting in a loss of integrity.
The vulnerability was reported in Tikiwiki version 1.9.4.
