An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-31294 exists.\n\nAffected packages and fixed versions:\n- keydb (Bitnami): affected all versions; fixed in 6.2.0\n- redis (Bitnami): affected all versions; fixed in 6.2.0\n- valkey (Bitnami): affected all versions; fixed in 6.2.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-31294/ (Markdown: https://insights.sbomify.com/CVE-2021-31294/index.md)","id":"CVE-2021-31294","markdown":"https://insights.sbomify.com/CVE-2021-31294/index.md","name":"CVE-2021-31294","record":{"aliases":["BIT-keydb-2021-31294","BIT-redis-2021-31294","BIT-valkey-2021-31294","DEBIAN-CVE-2021-31294","GHSA-g2jg-2qcv-q3h9","UBUNTU-CVE-2021-31294"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Redis database","requires_auth":"none","summary":"A malicious replica can crash the primary Redis server by sending a specific SET command, causing an assertion failure and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"redis","vendor":"redis"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"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).
