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-2026-27623/ (Markdown: https://insights.sbomify.com/CVE-2026-27623/index.md)","id":"CVE-2026-27623","markdown":"https://insights.sbomify.com/CVE-2026-27623/index.md","name":"CVE-2026-27623","record":{"aliases":["ALPINE-CVE-2026-27623","BIT-valkey-2026-27623","GHSA-93p9-5vc7-8wgr"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"valkey","vendor":"lfprojects"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Valkey is a distributed key-value database. Starting in version 9.0.0 and prior to version 9.0.3, a malicious actor with network access to Valkey can cause the system to abort by triggering an assertion. When processing incoming requests, the Valkey system does not properly reset the networking state after processing an empty request. A malicious actor can then send a request that the server incorrectly identifies as breaking server side invariants, which results in the server shutting down. Version 9.0.3 fixes the issue. As an additional mitigation, properly isolate Valkey deployments so that only trusted users have access.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Valkey has Pre-Authentication DOS from malformed RESP request","id":"CVE-2026-27623","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"Coturn: IPv4-mapped IPv6 (::ffff:0:0/96) bypasses denied-peer-ip ACL","id":"CVE-2026-27624"},"packages":[{"ecosystem":"Bitnami","fixed":["9.0.3"],"introduced":["9.0.0"],"last_affected":[],"package":"valkey","purl":"pkg:bitnami/valkey","source":"BIT-valkey-2026-27623"}],"prev":{"headline":"OpenEXR CompositeDeepScanLine integer-overflow leads to heap OOB write","id":"CVE-2026-27622"},"products":["valkey"],"published":"2026-02-23","related":[{"cvss_score":10,"headline":"Redis Lua Use-After-Free may lead to remote code execution","id":"CVE-2025-49844","kev_date_added":null,"published":"2025-10-03"},{"cvss_score":8.5,"headline":"Valkey Affected by RESP Protocol Injection via Lua error_reply","id":"CVE-2025-67733","kev_date_added":null,"published":"2026-02-23"},{"cvss_score":7.5,"headline":"Malformed Valkey Cluster bus message can lead to Remote DoS","id":"CVE-2026-21863","kev_date_added":null,"published":"2026-02-23"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-15","vendors":["valkey-io"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-27623/"}
