Spring Framework URL Parsing with Host Validation
Applications that use UriComponentsBuilder to parse an externally provided URL (e.g. through a query parameter) AND perform validation checks on the host of the parsed URL may be vulnerable to a  open redirect https://cwe.mitre.org/data/definitions/601.html  attack or to a SSRF attack if the URL is used after passing validation checks.

This is the same as  CVE-2024-22259 https://spring.io/security/cve-2024-22259  and  CVE-2024-22243 https://spring.io/security/cve-2024-22243 , but with different input.

Pivotal Spring Framework contains unsafe Java deserialization methods
Pivotal Spring Framework before 6.0.0 suffers from a potential remote code execution (RCE) issue if used for Java deserialization of untrusted data. Depending on how the library is implemented within a product, this issue may or not occur, and authentication may be required.

Maintainers recommend investigating alternative components or a potential mitigating control. Version 4.2.6 and 3.2.17 contain [enhanced documentation](https://github.com/spring-projects/spring-framework/commit/5cbe90b2cd91b866a5a9586e460f311860e11cfa) advising users to take precautions against unsafe Java deserialization, version 5.3.0 [deprecate the impacted classes](https://github.com/spring-projects/spring-framework/issues/25379) and version 6.0.0 [removed it entirely](https://github.com/spring-projects/spring-framework/issues/27422).

Spring Framework DoS via conditional HTTP request
### Description
Applications that parse ETags from `If-Match` or `If-None-Match` request headers are vulnerable to DoS attack.

### Affected Spring Products and Versions
org.springframework:spring-web in versions 

6.1.0 through 6.1.11
6.0.0 through 6.0.22
5.3.0 through 5.3.37

Older, unsupported versions are also affected

### Mitigation
Users of affected versions should upgrade to the corresponding fixed version.
6.1.x -> 6.1.12
6.0.x -> 6.0.23
5.3.x -> 5.3.38
No other mitigation steps are necessary.

Users of older, unsupported versions could enforce a size limit on `If-Match` and `If-None-Match` headers, e.g. through a Filter.

Improper Input Validation in Spring Framework
In Spring Framework versions 5.2.0 - 5.2.8, 5.1.0 - 5.1.17, 5.0.0 - 5.0.18, 4.3.0 - 4.3.28, and older unsupported versions, the protections against RFD attacks from CVE-2015-5211 may be bypassed depending on the browser used through the use of a jsessionid path parameter.
