Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Redis is an in-memory database that persists on disk. A specially crafted `XAUTOCLAIM` command on a stream key in a specific state may result with heap overflow, and potentially remote code execution. This problem affects versions on the 7.x branch prior to 7.0.4. The patch is released in version 7.0.4.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Heap overflow vulnerability in Redis XAUTOCLAIM command on stream keys in a specific state, potentially allowing remote code execution. The overflow occurs due to insufficient bounds checking when processing certain stream key states.

MitigationUpgrade Redis to version 7.0.4 or later to patch the heap overflow vulnerability. If immediate upgrade is not feasible, restrict access to Redis instances to trusted networks only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Redis version
    Run `redis-server --version` or `redis-cli INFO server` to retrieve the exact version number
    Affected if The version is >= 7.0.0 and < 7.0.4
  2. Identify active stream keys
    Use `redis-cli KEYS '*'` to find keys, then `redis-cli TYPE <key>` to identify stream types, or query `redis-cli XINFO STREAM <key>` on known stream keys
    Affected if Stream keys exist in the database and Redis version is in the affected range
  3. Verify XAUTOCLAIM command usage
    Enable slow logging with `redis-cli CONFIG SET slowlog-log-slower-than 0` and check `redis-cli SLOWLOG GET` for recent XAUTOCLAIM commands, or monitor with `redis-cli MONITOR`
    Affected if XAUTOCLAIM has been executed on stream keys and the Redis version is vulnerable
  4. Check network exposure
    Review Redis bind configuration with `redis-cli CONFIG GET bind` and firewall rules to determine if Redis is accessible from untrusted networks
    Affected if Redis is bound to non-localhost interfaces and is version vulnerable

A user is affected if their Redis version is 7.0.0 through 7.0.3 inclusive, they use stream keys, and the XAUTOCLAIM command has been or can be executed against stream keys in a vulnerable state.

Upgrade available Upgrade to 7.0.4 or later
Fixed in 7.0.4
Interim mitigation

Upgrade Redis to version 7.0.4 or later to patch the heap overflow vulnerability. If immediate upgrade is not feasible, restrict access to Redis instances to trusted networks only.

Recommended fix High confidence

Redis 7.0.4

  1. Backup your Redis data and configuration files
  2. Stop the Redis service
  3. Upgrade Redis to version 7.0.4 or later using your package manager or compilation (e.g., yum update redis, apt update redis, or compile from source)
  4. Verify the installed Redis version is 7.0.4 or later using `redis-server --version`
  5. Start the Redis service
  6. Test that the XAUTOCLAIM command works correctly on stream keys
Caveat Minor version upgrades within 7.0.x typically maintain backwards compatibility, but always test in staging first
