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-2026-46452 in the wild and no public exploit code.\n\nAffected product: Apache NimBLE. 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-2026-46452/ (Markdown: https://insights.sbomify.com/CVE-2026-46452/index.md)","id":"CVE-2026-46452","markdown":"https://insights.sbomify.com/CVE-2026-46452/index.md","name":"CVE-2026-46452","record":{"aliases":["GHSA-wfj4-rqg3-9346"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Bluetooth mesh library","requires_auth":"none","summary":"Attackers can cause memory pressure and unstable parsing in Apache NimBLE via improper input validation in Mesh Proxy SAR reassembly.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"nimble","vendor":"apache"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation vulnerability in Apache NimBLE in Mesh Proxy SAR reassembly could result in passing broken data toward application resulting in memory pressure and unstable parsing behavior.\n\nThis issue affects Apache NimBLE: through 1.9.0.\n\nUsers are recommended to upgrade to version 1.10.0, which fixes the issue.","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":"Apache NimBLE: Mesh Proxy SAR reassembly unbounded append and unchecked failure","id":"CVE-2026-46452","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":"Apache Camel-Elasticsearch-Rest-Client: Exchange header constants without the Camel prefix bypass inbound HTTP header filtering, allowing untrusted clients to override the Elasticsearch query and operation","id":"CVE-2026-46453"},"packages":[],"prev":{"headline":"Command injection in Guardicore Platform Agent","id":"CVE-2026-46449"},"products":["Apache NimBLE"],"published":"2026-07-24","related":[{"cvss_score":8.8,"headline":"Apache NimBLE: Incorrect data validation in BASS add/modify source operation","id":"CVE-2026-45813","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":8.1,"headline":"Apache Mynewt NimBLE: Incorrect handling of SMP Security Request could lead to undesirable pairing","id":"CVE-2025-62235","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":7.5,"headline":"Apache NimBLE: Buffer overflow in socket HCI transport","id":"CVE-2026-45811","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache NimBLE: Remote reachable assertion in ATT Read Multiple Variable Response handler","id":"CVE-2026-45815","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache NimBLE: NULL pointer dereference vulnerability in SMP LTK request","id":"CVE-2026-45816","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":7.5,"headline":"Apache Mynewt NimBLE: Invalid error handling in pause encryption procedure in NimBLE controller","id":"CVE-2025-52435","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":7.5,"headline":"Apache Mynewt NimBLE: NULL Pointer Dereference in NimBLE host HCI layer","id":"CVE-2025-53477","kev_date_added":null,"published":"2026-01-10"}],"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":"2026-07-24","vendors":["Apache Software Foundation"]},"summary":"Attackers can cause memory pressure and unstable parsing in Apache NimBLE via improper input validation in Mesh Proxy SAR reassembly.","url":"https://insights.sbomify.com/CVE-2026-46452/"}
