Technical Analysis

This vulnerability in Apache CouchDB affects the chttpd module's handling of binary deserialization. Specifically, unsafe deserialization can be exploited by an authenticated user to exhaust memory resources, leading to a denial of service condition. The flaw exists in all versions up to and including 3.5.2. The Apache Software Foundation has addressed this issue in version 3.5.3.

Potential Impact

An authenticated user can trigger a denial of service by causing memory exhaustion via unsafe binary deserialization. This disrupts service availability but does not affect confidentiality or integrity. The CVSS 4.0 score is 1.3, indicating low severity.

Mitigation Recommendations

Users should upgrade Apache CouchDB to version 3.5.3 or later, where this vulnerability is fixed. No other mitigation is indicated or required.
