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-2026-86452 in the wild and no public exploit code.\n\nAffected product: Misp-Project Misp. 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-2026-86452/ (Markdown: https://insights.sbomify.com/CVE-2026-86452/index.md)","id":"CVE-2026-86452","markdown":"https://insights.sbomify.com/CVE-2026-86452/index.md","name":"CVE-2026-86452","record":{"aliases":["GHSA-6crc-w8rh-cr5w"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing platform","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service by flooding MISP with unbounded password reset requests, consuming storage and resources.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[{"product":"misp","vendor":"misp-project"}],"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-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting.\n\nThe users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle.\n\nThe fix adds:\n\n - a maximum email input length of 1024 bytes;\n - email-format validation before persistent work;\n - a per-source pre-authentication request budget;\n - HTTP 429 responses when that budget is exceeded;\n - a 15-minute cooldown for API-access request emails;\n - POST-only handling and CSRF protection for the API-access request endpoint.\n\nThe new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts.\n\nVersion affected: ≤2.5.45","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":"MISP Unauthenticated Mail Endpoints Allow Unbounded Storage Consumption and Request Flooding","id":"CVE-2026-86452","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"misp-project:misp","products":["misp-project:misp"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Syncope: Cypher Injection via FIQL Search on Neo4j Persistence","id":"CVE-2026-86460"},"packages":[],"prev":{"headline":"MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects","id":"CVE-2026-86451"},"products":["MISP"],"published":"2026-09-07","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-46918","kev_date_added":null,"published":"2024-09-15"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-45509","kev_date_added":null,"published":"2024-09-01"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29858","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29859","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-25674","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-25675","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2023-50918","kev_date_added":null,"published":"2023-12-15"}],"sources":[{"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":"2026-09-14","vendors":["MISP"]},"summary":"Unauthenticated attackers can cause denial of service by flooding MISP with unbounded password reset requests, consuming storage and resources.","url":"https://insights.sbomify.com/CVE-2026-86452/"}
