CVE-2026-89314: CWE-407 Inefficient Algorithmic Complexity in Eclipse Foundation Eclipse KeyPont - GOSE
Description
CVE-2026-89314 is a medium severity vulnerability in Eclipse Foundation's Eclipse KeyPont - GOSE. It involves an inefficient algorithmic complexity issue in the jwkFields.CheckConsistency function, which uses a pairwise nested loop to detect duplicate key_ops entries. This causes the validation cost to grow quadratically with the number of entries. Since this check runs on every JWK and JWKS unmarshal, a specially crafted JWKS document could cause significant CPU consumption, potentially occupying a CPU core for many seconds.

Technical Analysis
The vulnerability CVE-2026-89314 in Eclipse KeyPont - GOSE arises from the jwkFields.CheckConsistency function's use of a pairwise nested loop to detect duplicate key_ops entries. This results in an inefficient algorithmic complexity where the validation cost grows with the square of the number of entries. Because this check is performed on every JWK and JWKS unmarshal operation, an attacker could craft a JWKS document with a modest number of entries that causes excessive CPU usage, leading to potential denial of service through resource exhaustion.
Potential Impact
The impact of this vulnerability is a potential denial of service condition caused by high CPU consumption during the unmarshalling of JWK and JWKS documents. A hostile JWKS document with duplicate key_ops entries can cause the validation process to consume CPU resources for many seconds, potentially degrading service availability or performance.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting the size and complexity of JWKS documents accepted by the system to reduce the risk of CPU exhaustion.
