Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50521 in the wild and no public exploit code.\n\nAffected product: Microsoft Edge Chromium. 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-2026-50521/ (Markdown: https://insights.sbomify.com/CVE-2026-50521/index.md)","id":"CVE-2026-50521","markdown":"https://insights.sbomify.com/CVE-2026-50521/index.md","name":"CVE-2026-50521","record":{"aliases":["GHSA-q4g4-rw2v-x4v7"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge browser","requires_auth":"low_privilege","summary":"An authorized attacker can execute arbitrary code remotely via a use-after-free flaw in Microsoft Edge.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"edge_chromium","vendor":"microsoft"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in Microsoft Edge (Chromium-based) allows an authorized attacker to execute code over a network.","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":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-50521","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:edge_chromium","products":["microsoft:edge_chromium"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft SharePoint Deserialization of Untrusted Data Vulnerability","id":"CVE-2026-50522"},"packages":[],"prev":{"headline":"Visual Studio Code Remote Code Execution Vulnerability","id":"CVE-2026-50520"},"products":["Microsoft Edge (Chromium-based)"],"published":"2026-07-01","related":[{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2024-21326","kev_date_added":null,"published":"2024-01-26"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2023-35618","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2023-36735","kev_date_added":null,"published":"2023-09-15"},{"cvss_score":9.6,"headline":"Microsoft Edge (Chromium-based) Security Feature Bypass Vulnerability","id":"CVE-2022-33649","kev_date_added":null,"published":"2022-08-09"},{"cvss_score":9,"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-58289","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":8.8,"headline":"Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability","id":"CVE-2026-69486","kev_date_added":null,"published":"2026-09-15"},{"cvss_score":8.8,"headline":"Microsoft Edge (Chromium-based) Elevation of Privilege Vulnerability","id":"CVE-2026-85893","kev_date_added":null,"published":"2026-09-15"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Microsoft"]},"summary":"An authorized attacker can execute arbitrary code remotely via a use-after-free flaw in Microsoft Edge.","url":"https://insights.sbomify.com/CVE-2026-50521/"}
