Application-object read and write via EL injection
Published Jun 11, 2026 · Updated Jun 11, 2026
Expression language injection in Spring Web Flow allows remote authenticated users to read or modify application objects via crafted requests. AbstractMvcView creates default data-binding targets by parsing each request-parameter name with the configured Unified EL parser rather than a property-only parser. Exploitation requires an ELExpressionParser, useSpringBinding disabled, view states without explicit binding declarations, low-privileged access, and user interaction.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2.5.0 <2.5.2
- Affected versionversion=3.0.0 <3.0.2
- Affected versionversion=4.0.0 <4.0.1
