CVE-2021-31294: Redis

Medium severity, CVSS 5.9. EPSS: 1.3% chance of exploitation in the next 30 days.

Redis before 6cbea7d allows a replica to cause an assertion failure in a primary server by sending a non-administrative command (specifically, a SET command). NOTE: this was fixed for Redis 6.2.x and 7.x in 2021. Versions before 6.2 were not intended to have safety guarantees related to this.

Affected products

• Redis Redis: before 6.2.0 (fixed in 6.2.0)
