spring-expression is vulnerable to Expression Language Injection
65
Medium Risk
This Affects:
spring-expressionTL;DR
spring-expression can compile expressions evaluated under SimpleEvaluationContext when the compiler is in IMMEDIATE or MIXED mode. Compiled evaluation then skips the safety guards that interpreted evaluation enforces. Untrusted expressions can therefore do more than SimpleEvaluationContext allows. The patch keeps those guards in place for compiled expressions.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and SpEL is evaluated with SimpleEvaluationContext while the expression compiler is in IMMEDIATE or MIXED mode.
Background info
spring-expression is vulnerable to Expression Language Injection in versions 0.0.1 - 7.0.8.
How to fix this
Upgrade the org.springframework:spring-expression library to the patch version.
