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-2026-59323 in the wild and no public exploit code.\n\nAffected product: Spring Micrometer Tracing. 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-2026-59323/ (Markdown: https://insights.sbomify.com/CVE-2026-59323/index.md)","id":"CVE-2026-59323","markdown":"https://insights.sbomify.com/CVE-2026-59323/index.md","name":"CVE-2026-59323","record":{"aliases":["CLSA-2026-1792395367","CLSA-2026-1792395420","GHSA-rj39-56xf-v987"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Java tracing library","requires_auth":"none","summary":"Attackers can cause denial of service via unbounded memory allocation in Micrometer Tracing when W3C baggage propagation is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"An application using Micrometer Tracing with W3C baggage propagation in the Brave bridge is vulnerable to denial of service (DoS) due to unbounded object allocation when extracting incoming baggage headers.\nMicrometer Tracing 1.7.0\nMicrometer Tracing 1.6.0 - 1.6.6\nMicrometer Tracing 1.5.0 - 1.5.12\nMicrometer Tracing 1.4.13 and earlier","ecosystems":[],"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":"Micrometer Tracing Brave Bridge W3C Baggage propagation DoS vulnerability","id":"CVE-2026-59323","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"fluxTransform shared RequestMessageHolder causes cross-message header leakage under async fluxFunction","id":"CVE-2026-59324"},"packages":[],"prev":{"headline":"EmbeddedHeadersJsonMessageMapper default gives wire peer full control of MessageHeaders","id":"CVE-2026-59322"},"products":["Micrometer Tracing"],"published":"2026-08-21","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":"2026-08-27","vendors":["Spring"]},"summary":"Attackers can cause denial of service via unbounded memory allocation in Micrometer Tracing when W3C baggage propagation is enabled.","url":"https://insights.sbomify.com/CVE-2026-59323/"}
