CPU Exhaustion

Neethi is vulnerable to CPU Exhaustion. The vulnerability is due to an exponential‑time algorithm in Neethi's policy‑intersection logic, where a specially crafted pair of WS‑Policy documents trigger the policy-intersection routine to perform exponential work, pinning the CPU for an extended perio...

The Cost of Stability: Deanonymizing Onion Services Long-Lived Introduction Circuits

Tor is a widely used anonymity network that provides network privacy by routing client communications through a sequence of relays to their destinations. An adversary observing a single Tor relay cannot readily link clients to their destinations, as doing so requires identifying the other relays...

CVE-2026-91866

A flaw was found in Neethi. A remote attacker could exploit this vulnerability by providing specially crafted WS-Policy documents. This could force Neethi's policy-intersection to perform an exponential amount of work, leading to a denial of service DoS by consuming excessive CPU resources...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the policy-intersection. An attacker can exhaust system resources and cause service disruption by submitting specially crafted WS-Policy documents that trigger excessive...

CVE-2026-91866

A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time denial of service. Users are recommended to upgrade to version 3.2.4, which fixes this issue...

CVE-2026-91866 Apache Neethi: Crafted policies cause unbounded work during intersection leading to denial of service

A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time denial of service. Users are recommended to upgrade to version 3.2.4, which fixes this issue...

CVE-2026-91866

Apache Neethi is vulnerable to a denial of service (DoS) condition due to a flaw in its policy-intersection functionality.
