CVE-2026-66144: Apache Neethi: Remote PolicyReference fetch lacks resource bounds

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV

• Public exploit or detection template: none known
• Published: 2026-07-24 · updated 2026-10-24
• Weakness: CWE-400

Description

Although remote policy references are not retrieved during policy normalization, if they are manually retrieved via the API it can cause a denial of service attack if a huge policy is retrieved. Users are recommended to upgrade to version 3.2.3, which fixes this issue by imposing a default maximum size on data read from remote policy references.

Affected products

• Apache Software Foundation Apache Neethi: before 3.2.3 — fixed in 3.2.3

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Neethi 3.2.3. Check the vendor advisory for mitigations.
