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-2023-35311 and fix it if it is affected.\n\nWhat it is: CVE-2023-35311 is a high-severity vulnerability in Microsoft 365 Apps, published on 11 Jul 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2023-35311 in the wild since at least 11 Jul 2023.\n\nAffected product: Microsoft 365 Apps. 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-2023-35311/ (Markdown: https://insights.sbomify.com/CVE-2023-35311/index.md)","id":"CVE-2023-35311","markdown":"https://insights.sbomify.com/CVE-2023-35311/index.md","name":"CVE-2023-35311","record":{"aliases":["GHSA-3w2f-j9r3-9h89"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Outlook","requires_auth":"none","summary":"Attackers can bypass security features in Microsoft Outlook, potentially exposing users to malicious content or actions.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_apps","vendor":"microsoft"},{"product":"office_2019","vendor":"microsoft"},{"product":"office_2021","vendor":"microsoft"},{"product":"outlook","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:F/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Microsoft Outlook Security Feature Bypass Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Outlook Security Feature Bypass","id":"CVE-2023-35311","indexable":true,"kev":{"dateAdded":"2023-07-11","dueDate":"2023-08-01","knownRansomwareCampaignUse":"Unknown","product":"Outlook","requiredAction":"Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Outlook Security Feature Bypass Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_apps","products":["microsoft:365_apps","microsoft:office_2019","microsoft:office_2021","microsoft:outlook"],"type":"security_feature_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft VOLSNAP.SYS Elevation of Privilege Vulnerability","id":"CVE-2023-35312"},"packages":[],"prev":{"headline":"Windows DNS Server Remote Code Execution Vulnerability","id":"CVE-2023-35310"},"products":["Microsoft 365 Apps for Enterprise","Microsoft Office 2019","Microsoft Office LTSC 2021","Microsoft Outlook 2013","Microsoft Outlook 2013 Service Pack 1","Microsoft Outlook 2016"],"published":"2023-07-11","related":[{"cvss_score":9.8,"headline":"Microsoft Outlook Improper Input Validation","id":"CVE-2024-21413","kev_date_added":"2025-02-06","published":"2024-02-13"},{"cvss_score":9.8,"headline":"Microsoft Office Outlook Privilege Escalation","id":"CVE-2023-23397","kev_date_added":"2023-03-14","published":"2023-03-14"},{"cvss_score":8.8,"headline":"Microsoft Project Remote Code Execution Vulnerability","id":"CVE-2024-38189","kev_date_added":"2024-08-13","published":"2024-08-13"},{"cvss_score":7.8,"headline":"Microsoft Office Word Reliance on Untrusted Inputs in a Security Decision","id":"CVE-2026-21514","kev_date_added":"2026-02-10","published":"2026-02-10"},{"cvss_score":7.8,"headline":"Microsoft Office Security Feature Bypass","id":"CVE-2026-21509","kev_date_added":"2026-01-26","published":"2026-01-26"},{"cvss_score":7.8,"headline":"Microsoft Excel Security Feature Bypass","id":"CVE-2021-42292","kev_date_added":"2021-11-17","published":"2021-11-10"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-07","vendors":["Microsoft"]},"summary":"Attackers can bypass security features in Microsoft Outlook, potentially exposing users to malicious content or actions.","url":"https://insights.sbomify.com/CVE-2023-35311/"}
