Description

This security bulletin contains information about 4 vulnerabilities.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-57819)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource allocation in the JAX-RS form parameter processing in cxf-rt-frontend-jaxrs when handling requests with very large numbers of form parameters. A remote attacker can send a specially crafted request to cause a denial of service.


2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-54225)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource control in attachment processing when handling large attachments without a configured maximum attachment size. A remote attacker can send a specially crafted request with a large attachment to cause a denial of service.

Only deployments that do not explicitly configure an attachment size limit are vulnerable.


3) Input validation error (CVE-ID: CVE-2026-64958)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper input validation in message header attachment processing when handling messages with many attachment headers. A remote attacker can send a specially crafted message to cause a denial of service.


4) Resource exhaustion (CVE-ID: CVE-2026-50645)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to there is no restriction on the amount of attachment headers that a message can contain when being deserialized by Apache CXF. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
