An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-50879 exists.\n\nAffected packages and fixed versions:\n- github.com/andreimarcu/linx-server (Go): affected all versions; no fix listed\n- github.com/andreimarcu/linx-server (Go): affected all versions up to 2.3.8; no fix listed\n- github.com/andreimarcu/linx-server (Go): affected all versions up to 2.3.8; no fix listed\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-2026-50879/ (Markdown: https://insights.sbomify.com/CVE-2026-50879/index.md)","id":"CVE-2026-50879","markdown":"https://insights.sbomify.com/CVE-2026-50879/index.md","name":"CVE-2026-50879","record":{"aliases":["GHSA-g743-m6x3-v6wm","GO-2026-6297"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go web server","requires_auth":"none","summary":"Attackers can cause a Denial of Service in linx-server by sending a crafted POST request to the upload handler.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"An issue in the uploadPostHandler component of Andrei Marcu linx-server v2.3.8 allows attackers to cause a Denial of Service (DoS) via a crafted POST request.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"linx-server has an issue in the uploadPostHandler component that allows attackers to cause a Denial of Service (DoS) via a crafted POST request","id":"CVE-2026-50879","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"YouTransfer has an issue in the sendmail transport integration that allows arbitrary code execution","id":"CVE-2026-50880"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/andreimarcu/linx-server","purl":"pkg:golang/github.com/andreimarcu/linx-server","source":"GO-2026-6297"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.3.8"],"package":"github.com/andreimarcu/linx-server","purl":null,"source":"GHSA-g743-m6x3-v6wm"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.3.8"],"package":"github.com/andreimarcu/linx-server","purl":"pkg:golang/github.com/andreimarcu/linx-server","source":"GHSA-g743-m6x3-v6wm"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2026-50878"},"products":["n/a"],"published":"2026-06-15","related":[],"sources":[{"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-16","vendors":["n/a"]},"summary":"Attackers can cause a Denial of Service in linx-server by sending a crafted POST request to the upload handler.","url":"https://insights.sbomify.com/CVE-2026-50879/"}
