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-2026-47138 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- parse-server (npm): affected all versions; fixed in 8.6.77\n- parse-server (npm): affected all versions; fixed in 8.6.77\n- parse-server (npm): affected from 9.0.0; fixed in 9.9.1-alpha.1\n- parse-server (npm): affected from 9.0.0; fixed in 9.9.1-alpha.1\n- parse (Bitnami): affected all versions; fixed in 8.6.77, 9.9.1\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-2026-47138/ (Markdown: https://insights.sbomify.com/CVE-2026-47138/index.md)","id":"CVE-2026-47138","markdown":"https://insights.sbomify.com/CVE-2026-47138/index.md","name":"CVE-2026-47138","record":{"aliases":["BIT-parse-2026-47138","GHSA-38m6-82c8-4xfm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Parse Server backend","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service in Parse Server by sending crafted HTTP headers that trigger regex backtracking, saturating CPU resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.77 and 9.9.1-alpha.1, an unauthenticated attacker who knows a publicly-known Parse Application ID can submit a single HTTP request whose client SDK version field contains adversarial input that triggers polynomial backtracking in a request-header parser. The parsing runs before session authentication and before rate limiting on every /parse/* request, so the request consumes seconds to minutes of synchronous CPU on a Node.js worker before any access control evaluates it. A small number of concurrent requests can saturate a worker; a single large request via the body-field variant can pin a worker for minutes. Production deployments running the default configuration are affected. This issue has been patched in versions 8.6.77 and 9.9.1-alpha.1.","ecosystems":["Bitnami","npm"],"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":"Parse Server: Pre-authentication denial of service via client version header regex backtracking","id":"CVE-2026-47138","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":5,"n_references":3,"next":{"headline":"vm2: NodeVM network builtin exclusions bypass via internal _http_client and _http_server","id":"CVE-2026-47139"},"packages":[{"ecosystem":"Bitnami","fixed":["8.6.77","9.9.1"],"introduced":["0","9.0.0"],"last_affected":[],"package":"parse","purl":"pkg:bitnami/parse","source":"BIT-parse-2026-47138"},{"ecosystem":"npm","fixed":["8.6.77"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-38m6-82c8-4xfm"},{"ecosystem":"npm","fixed":["8.6.77"],"introduced":["0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-38m6-82c8-4xfm"},{"ecosystem":"npm","fixed":["9.9.1-alpha.1"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":null,"source":"GHSA-38m6-82c8-4xfm"},{"ecosystem":"npm","fixed":["9.9.1-alpha.1"],"introduced":["9.0.0"],"last_affected":[],"package":"parse-server","purl":"pkg:npm/parse-server","source":"GHSA-38m6-82c8-4xfm"}],"prev":{"headline":"vm2: GHSA-8hg8-63c5-gwmx patch bypass: nesting:true without explicit require still allows full RCE","id":"CVE-2026-47137"},"products":["parse-server"],"published":"2026-06-12","related":[],"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":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2026-06-12","vendors":["parse-community"]},"summary":"Unauthenticated attackers can cause denial of service in Parse Server by sending crafted HTTP headers that trigger regex backtracking, saturating CPU resources.","url":"https://insights.sbomify.com/CVE-2026-47138/"}
