In Spring Framework versions 5.3.0 - 5.3.38 and older unsupported versions, it is possible for a user to provide a specially crafted Spring Expression Language (SpEL) expression that may cause a denial of service (DoS) condition.
Specifically, an application is vulnerable when the following is true:
[
{
"defaultStatus": "affected",
"packageName": "Spring Framework",
"product": "Spring Framework",
"vendor": "Spring",
"versions": [
{
"lessThan": "5.3.39, 6.0+",
"status": "affected",
"version": "5.3.0",
"versionType": "5.3.396.0"
}
]
}
]
