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-2026-59675 in the wild and no public exploit code.\n\nAffected product: SUSE Rancher. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-59675/ (Markdown: https://insights.sbomify.com/CVE-2026-59675/index.md)","id":"CVE-2026-59675","markdown":"https://insights.sbomify.com/CVE-2026-59675/index.md","name":"CVE-2026-59675","record":{"aliases":["GHSA-g4f6-44g4-23xm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Rancher management platform","requires_auth":"none","summary":"Unauthenticated attackers can cause memory exhaustion and service outage in Rancher Manager by sending large payloads to login endpoints when audit logging is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"When API audit logging is enabled, the middleware reads the entire HTTP request body into memory without enforcing a size limit on login endpoints. Because the audit middleware is positioned earlier in the handler chain than Rancher's APIBodyLimitingHandler, the body-size cap (default 1 MiB) is bypassed for requests that pass through the audit copyReqBody path. An unauthenticated attacker can send arbitrarily large request bodies to the public login endpoints, causing the Rancher Manager server process to allocate memory proportional to the supplied body size. With just a few concurrent connections, this can exhaust available memory and terminate the Rancher Manager plane process, making the Rancher API and UI unavailable and interrupting management of all downstream clusters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Rancher Audit-Log Middleware Unauthenticated Memory Exhaustion Denial of Service","id":"CVE-2026-59675","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Local File Deletion Attack Vector in rm_rf() in seunshare","id":"CVE-2026-59676"},"packages":[],"prev":{"headline":"LPE from suricata user to root due to chown in %post in suricata packaging","id":"CVE-2026-59674"},"products":["Rancher"],"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-05","vendors":["SUSE"]},"summary":"Unauthenticated attackers can cause memory exhaustion and service outage in Rancher Manager by sending large payloads to login endpoints when audit logging is enabled.","url":"https://insights.sbomify.com/CVE-2026-59675/"}
