A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi copies into memory without counting it against its size limits, exhausting the heap (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.

The version of IBM WebSphere Application Server Liberty running on the remote host is affected by a DoS vulnerability as referenced in the 7295364 advisory.

  - A small WS-Policy document using repeated policy references can force Neethi to re-expand the same     references exponentially during normalization, consuming huge amounts of CPU and memory (denial of     service). Users are recommended to upgrade to version 3.2.4, which fixes this issue. (CVE-2026-91865)

  - A specially crafted WS-Policy document with deeply nested policy elements can bypass Neethi's nesting-     depth limit and exhaust the thread stack, crashing the parser (denial of service). Users are recommended     to upgrade to version 3.2.4, which fixes this issue. (CVE-2026-91863)

  - A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi     copies into memory without counting it against its size limits, exhausting the heap (denial of service).
    Users are recommended to upgrade to version 3.2.4, which fixes this issue. (CVE-2026-91864)
