Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-1647 in the wild and no public exploit code.\n\nAffected product: calcom/cal.com. 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-2023-1647/ (Markdown: https://insights.sbomify.com/CVE-2023-1647/index.md)","id":"CVE-2023-1647","markdown":"https://insights.sbomify.com/CVE-2023-1647/index.md","name":"CVE-2023-1647","record":{"aliases":["GHSA-976q-qhh2-p88c"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cal.com scheduling app","requires_auth":"low_privilege","summary":"Attackers can bypass access controls to read or modify data in the Cal.com scheduling application.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"cal.com","vendor":"cal"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Improper Access Control in GitHub repository calcom/cal.com prior to 2.7.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Improper Access Control in calcom/cal.com","id":"CVE-2023-1647","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"ChatBot \u003c 4.5.1 - Admin+ Stored XSS","id":"CVE-2023-1649"},"packages":[],"prev":{"headline":"IObit Malware Fighter IOCTL IMFCameraProtect.sys 0x8018E004 stack-based overflow","id":"CVE-2023-1646"},"products":["calcom/cal.com"],"published":"2023-03-27","related":[{"cvss_score":10,"headline":"Cal.com has an Authentication Bypass via Unvalidated Email in Custom JWT Callback","id":"CVE-2026-23478","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":9.9,"headline":"Cal.com Authentication Bypass via bad TOTP + password checks","id":"CVE-2025-66489","kev_date_added":null,"published":"2025-12-03"},{"cvss_score":6.5,"headline":"Cal.com not expiring old sessions after enabling 2FA","id":"CVE-2023-37919","kev_date_added":null,"published":"2023-07-25"}],"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":"2025-02-19","vendors":["calcom"]},"summary":"Attackers can bypass access controls to read or modify data in the Cal.com scheduling application.","url":"https://insights.sbomify.com/CVE-2023-1647/"}
