Hi, The following vulnerability was published for valkey. CVE-2026-63639[0]: | Valkey is a distributed key-value database. Prior to 7.2.14, 8.0.10, | 8.1.9, 9.0.5, and 9.1.1, Valkey's RESTORE command accepts a | malformed RDB stream payload that assigns one Pending Entry List | NACK to multiple consumers during stream consumer-group | deserialization, causing a use-after-free when one consumer is | deleted while another still references the shared NACK and | potentially allowing remote code execution. This issue is fixed in | versions 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
