An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-24301 and fix it if it is affected.\n\nWhat it is: CVE-2026-24301 is a high-severity command injection vulnerability in Microsoft Copilot Web, published on 18 Aug 2026. 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-2026-24301 in the wild and no public exploit code.\n\nAffected product: Microsoft Copilot Web. 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-2026-24301/ (Markdown: https://insights.sbomify.com/CVE-2026-24301/index.md)","id":"CVE-2026-24301","markdown":"https://insights.sbomify.com/CVE-2026-24301/index.md","name":"CVE-2026-24301","record":{"aliases":["GHSA-9q66-w589-xv8x"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Copilot Web","requires_auth":"none","summary":"An unauthorized attacker can exploit command injection in Microsoft Copilot Web to disclose sensitive information over the network.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"copilot","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"Improper neutralization of special elements used in a command ('command injection') in Microsoft Copilot allows an unauthorized attacker to disclose information over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-20","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-20T11:25:55Z","kind":"github_poc","ref":"https://github.com/CSOAI-ORG/memory-poisoning-axis","stars":0,"title":"🧪 Measures memory-poisoning / prompt-injection deterministically — anchored to CVE-2026-24301 (CoSnitch), Inspect scorer, signed receipts.
