Description
CVE-2024-38820 ensured Locale-independent, lowercase conversion for both the configured disallowedFields patterns and for request parameter names. However, there are still cases where it is possible to bypass the disallowedFields checks.
Affected Spring Products and Versions
Spring Framework:
-
6.2.0 - 6.2.6
-
6.1.0 - 6.1.19
-
6.0.0 - 6.0.27
-
5.3.0 - 5.3.42
-
Older, unsupported versions are also affected
Mitigation
Users of affected versions should upgrade to the corresponding fixed version.
| Affected version(s) | Fix Version | Availability |
|---|---|---|
| 6.2.x | 6.2.7 | OSS |
| 6.1.x | 6.1.20 | OSS |
| 6.0.x | 6.0.28 | Commercial https://enterprise.spring.io/ |
| 5.3.x | 5.3.43 | Commercial https://enterprise.spring.io/ |
No further mitigation steps are necessary.
Generally, we recommend using a dedicated model object with properties only for data binding, or using constructor binding since constructor arguments explicitly declare what to bind together with turning off setter binding through the declarativeBinding flag. See the Model Design section in the reference documentation.
For setting binding, prefer the use of allowedFields (an explicit list) over disallowedFields.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework:spring-context, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.springframework:spring-context to 6.2.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-22233 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
