CVE-2025-48795 — Apache CXF stores large stream based messages as temporary files on the local filesystem
Apache CXF stores large stream based messages as temporary files on the local filesystem. A bug was introduced which means that the entire temporary file is read into memory and then logged. An attacker might be able to exploit this to cause a denial of service attack by causing an out of memory exception. In addition, it is possible to configure CXF to encrypt temporary files to prevent sensitive credentials from being cached unencrypted on the local filesystem, however this bug means that the cached files are written out to logs unencrypted. Users are recommended to upgrade to versions 3.5.11, 3.6.6, 4.0.7 or 4.1.1, which fixes this issue.

Matched remediation archetype
Resource exhaustion and denial of service
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
- Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
- Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.
Remediate safely
- Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
- Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
- Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
