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-2026-40050 in the wild and no public exploit code.\n\nAffected product: CrowdStrike LogScale Self-Hosted. 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-2026-40050/ (Markdown: https://insights.sbomify.com/CVE-2026-40050/index.md)","id":"CVE-2026-40050","markdown":"https://insights.sbomify.com/CVE-2026-40050/index.md","name":"CVE-2026-40050","record":{"aliases":["GHSA-q4qj-hj7m-7jgx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"CrowdStrike LogScale","requires_auth":"none","summary":"Remote attackers can read arbitrary files from the server filesystem via an unauthenticated path traversal in specific LogScale cluster API endpoints.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CrowdStrike","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"CrowdStrike has released security updates to address a critical unauthenticated path traversal vulnerability (CVE-2026-40050) in LogScale. This vulnerability only requires mitigation by customers that host specific versions of LogScale and does not affect Next-Gen SIEM customers. The vulnerability exists in a specific cluster API endpoint that, if exposed, allows a remote attacker to read arbitrary files from the server filesystem without authentication.\n\nNext-Gen SIEM customers are not affected and do not need to take any action. CrowdStrike mitigated the vulnerability for LogScale SaaS customers by deploying network-layer blocks to all clusters on April 7, 2026. We have proactively reviewed all log data and there is no evidence of exploitation.\n\nLogScale Self-hosted customers should upgrade to a patched version immediately to remediate the vulnerability.\n\nCrowdStrike identified this vulnerability during continuous and ongoing product testing.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"CrowdStrike LogScale Unauthenticated Path Traversal","id":"CVE-2026-40050","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vulnerability Affecting Office Macro Removal in CrowdStrike Falcon Sensor for Windows","id":"CVE-2026-40058"},"packages":[],"prev":{"headline":"Apache Camel PQC: Unsafe Deserialization from FileBasedKeyLifecycleManager","id":"CVE-2026-40048"},"products":["LogScale Self-Hosted"],"published":"2026-04-21","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":"total"},"state":"PUBLISHED","updated":"2026-04-21","vendors":["CrowdStrike"]},"summary":"Remote attackers can read arbitrary files from the server filesystem via an unauthenticated path traversal in specific LogScale cluster API endpoints.","url":"https://insights.sbomify.com/CVE-2026-40050/"}
