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-2026-45044 exists.\n\nAffected product: rustfs. 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-2026-45044/ (Markdown: https://insights.sbomify.com/CVE-2026-45044/index.md)","id":"CVE-2026-45044","markdown":"https://insights.sbomify.com/CVE-2026-45044/index.md","name":"CVE-2026-45044","record":{"aliases":["GHSA-8784-9m7f-c6p6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"RustFS object storage","requires_auth":"none","summary":"Unauthenticated attackers can access profiling endpoints to cause denial of service and leak filesystem paths in RustFS.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the admin router explicitly whitelists /profile/cpu and /profile/memory from the authentication layer, allowing any unauthenticated HTTP client to invoke profiling handlers without credentials. On supported builds (e.g., glibc), the handler invokes a fixed 60-second CPU profiling operation (dump_cpu_pprof_for(Duration::from_secs(60))). This may result in significant CPU resource consumption per request and can potentially lead to denial of service when abused. Additionally, the handler returns the server’s absolute filesystem path in the response body, resulting in information disclosure. This vulnerability is fixed in 1.0.0-beta.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"RustFS: Authentication bypass in /profile/cpu and /profile/memory allows unauthenticated access to profiling handlers","id":"CVE-2026-45044","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Fiber: X-Real-IP Spoofing via Header.Add() in BalancerForward","id":"CVE-2026-45045"},"packages":[],"prev":{"headline":"RustFS: ImportIam Allows Creation of Backdoor Service Accounts Under Any Parent Including Root","id":"CVE-2026-45043"},"products":["rustfs"],"published":"2026-05-28","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-28","vendors":["rustfs"]},"summary":"Unauthenticated attackers can access profiling endpoints to cause denial of service and leak filesystem paths in RustFS.","url":"https://insights.sbomify.com/CVE-2026-45044/"}
