Spring Framework Arbitrary Method Invocation in SpEL Expressions
A vulnerability in Spring Expression Language (SpEL) evaluation logic allows for arbitrary zero-argument method invocation, even within restricted or read-only contexts, which may allow an attacker to invoke unintended application logic.
Affected versions:
Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.
An attacker who can supply user-controlled SpEL expressions can invoke arbitrary zero-argument methods even within restricted or read-only SpEL contexts, potentially triggering unintended application logic.
CAPEC ID: N/A
Description: An attacker who can supply user-controlled SpEL expressions can invoke arbitrary zero-argument methods even within restricted or read-only SpEL contexts, potentially triggering unintended application logic.
