Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson library, and result with heap corruption and potentially remote code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users. The problem is fixed in versions 7.0.12, 6.2.13, and 6.0.20.
CVE-2022-24834
Score elevated to 7.4 because EPSS predicts 41% probability of exploitation within the next 30 days (top 1.5% of all CVEs). NVD baseline CVSS 7.0 retained for reference. Confidence: see factors.
