An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47784 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- memcached (Bitnami): affected all versions; fixed in 1.6.42\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-2026-47784/ (Markdown: https://insights.sbomify.com/CVE-2026-47784/index.md)","id":"CVE-2026-47784","markdown":"https://insights.sbomify.com/CVE-2026-47784/index.md","name":"CVE-2026-47784","record":{"aliases":["AZL-87005","BIT-memcached-2026-47784","DEBIAN-CVE-2026-47784","GHSA-r4h3-4q3v-2776","MINI-56gj-c53w-xq59","MINI-cjxc-jwc7-rpvg","RHSA-2026:23261","UBUNTU-CVE-2026-47784"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"memcached server","requires_auth":"none","summary":"An attacker can exploit a timing side channel in SASL authentication to potentially recover password data from memcached.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"memcached","vendor":"memcached"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"In memcached before 1.6.42, password data for SASL password database authentication has a timing side channel because memcmp is used by sasl_server_userdb_checkpass.","ecosystems":["Bitnami","Red Hat:hummingbird:1"],"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":"Information disclosure in memcached","id":"CVE-2026-47784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Pre-Authentication Command Injection","id":"CVE-2026-47786"},"packages":[{"ecosystem":"Bitnami","fixed":["1.6.42"],"introduced":["0"],"last_affected":[],"package":"memcached","purl":"pkg:bitnami/memcached","source":"BIT-memcached-2026-47784"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.6.42-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"memcached","purl":"pkg:rpm/redhat/memcached","source":"RHSA-2026:23261"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.6.42-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"memcached-devel","purl":"pkg:rpm/redhat/memcached-devel","source":"RHSA-2026:23261"},{"ecosystem":"Red Hat:hummingbird:1","fixed":["0:1.6.42-0.1.hum1"],"introduced":["0"],"last_affected":[],"package":"memcached-selinux","purl":"pkg:rpm/redhat/memcached-selinux","source":"RHSA-2026:23261"}],"prev":{"headline":"Information disclosure in memcached","id":"CVE-2026-47783"},"products":["memcached"],"published":"2026-05-20","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46853","kev_date_added":null,"published":"2023-10-27"},{"cvss_score":9.8,"headline":"Integer overflow in Memcached","id":"CVE-2016-8704","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":9.8,"headline":"Integer overflow in Memcached","id":"CVE-2016-8705","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":8.1,"headline":"Information disclosure in memcached","id":"CVE-2026-47783","kev_date_added":null,"published":"2026-05-20"},{"cvss_score":8.1,"headline":"Integer overflow in Memcached","id":"CVE-2016-8706","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2023-46852","kev_date_added":null,"published":"2023-10-27"}],"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":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-20","vendors":["memcached"]},"summary":"An attacker can exploit a timing side channel in SASL authentication to potentially recover password data from memcached.","url":"https://insights.sbomify.com/CVE-2026-47784/"}
