The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when handling untrusted input passed to the org.apache.commons.io.input.XmlStreamReader class. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Uncontrolled Recursion (CVE-ID: CVE-2025-53864)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack via a deeply nested JSON object supplied in a JWT claim set.


3) Race condition (CVE-ID: CVE-2025-12383)

The vulnerability allows a remote attacker to bypass trust restrictions.

4) Protection Mechanism Failure (CVE-ID: CVE-2025-41249)

The vulnerability allows a remote attacker to gain access to sensitive information. 

The vulnerability exists due to the annotation detection mechanism may not correctly resolve annotations on methods within type hierarchies with a parameterized super type with unbounded generics. A remote attacker can gain access to sensitive information. 


5) Resource exhaustion (CVE-ID: CVE-2025-48976)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to Apache Commons FileUpload provided a hard-coded limit of 10kB for the size of the headers associated with a multipart request. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
