An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-47644 in the wild and no public exploit code.\n\nAffected product: Copilot Chat (Microsoft Edge). 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-2026-47644/ (Markdown: https://insights.sbomify.com/CVE-2026-47644/index.md)","id":"CVE-2026-47644","markdown":"https://insights.sbomify.com/CVE-2026-47644/index.md","name":"CVE-2026-47644","record":{"aliases":["GHSA-6w62-wfvj-6pfp"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Edge Copilot Chat","requires_auth":"none","summary":"An injection flaw in Microsoft Edge Copilot Chat allows attackers to disclose sensitive information over the network.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"copilot_chat","vendor":"microsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Improper neutralization of special elements in output used by a downstream component ('injection') in Copilot Chat (Microsoft Edge) allows an unauthorized attacker to disclose information over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-15","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-15T05:22:05Z","kind":"github_poc","ref":"https://github.com/songjianyang/CVE-2026-47644","stars":4,"title":"CVE-2026-47644 ($12,000): Edge Copilot Prompt Injection Leads to Cross-Tab Data Exfiltration - PoC \u0026 full writeup"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Copilot Chat (Microsoft Edge) Information Disclosure Vulnerability","id":"CVE-2026-47644","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft 365 Copilot's Business Chat Elevation of Privilege Vulnerability","id":"CVE-2026-47645"},"packages":[],"prev":{"headline":"Azure Stack Edge Remote Code Execution Vulnerability","id":"CVE-2026-47643"},"products":["Copilot Chat (Microsoft Edge)"],"published":"2026-06-04","related":[{"cvss_score":7.5,"headline":"Copilot Chat (Microsoft Edge) Information Disclosure Vulnerability","id":"CVE-2026-33111","kev_date_added":null,"published":"2026-05-07"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Microsoft"]},"summary":"An injection flaw in Microsoft Edge Copilot Chat allows attackers to disclose sensitive information over the network.","url":"https://insights.sbomify.com/CVE-2026-47644/"}
