Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-45644 and fix it if it is affected.\n\nWhat it is: CVE-2026-45644 is a high-severity cross-site scripting vulnerability in Microsoft Live Share Canvas SDK, published on 9 Jun 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-45644 in the wild and no public exploit code.\n\nAffected product: Microsoft Live Share Canvas SDK. 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-2026-45644/ (Markdown: https://insights.sbomify.com/CVE-2026-45644/index.md)","id":"CVE-2026-45644","markdown":"https://insights.sbomify.com/CVE-2026-45644/index.md","name":"CVE-2026-45644","record":{"aliases":["GHSA-pc2q-pf7r-rf2w"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Live Share Canvas SDK","requires_auth":"low_privilege","summary":"An authorized attacker can exploit a cross-site scripting flaw in the Microsoft Live Share Canvas SDK to elevate privileges over the network.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"live_share_canvas","vendor":"microsoft"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Live Share Canvas SDK allows an authorized attacker to elevate privileges 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 Live Share Canvas SDK Elevation of Privilege Vulnerability","id":"CVE-2026-45644","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Remote Code Execution Vulnerability","id":"CVE-2026-45645"},"packages":[],"prev":{"headline":"Microsoft Word Remote Code Execution Vulnerability","id":"CVE-2026-45643"},"products":["Microsoft Live Share Canvas SDK"],"published":"2026-06-09","related":[],"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 exploit a cross-site scripting flaw in the Microsoft Live Share Canvas SDK to elevate privileges over the network.","url":"https://insights.sbomify.com/CVE-2026-45644/"}
