Spring Framework Arbitrary Method Invocation in SpEL Expressions
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: org.springframework:spring-expression (Maven) 6.2.19, 7.0.8.
Low priority for now. Upgrade to org.springframework:spring-expression (Maven) 6.2.19, 7.0.8 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
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.
