Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-16624 exists.\n\nAffected product: Cal.com Cal.diy. 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-2026-16624/ (Markdown: https://insights.sbomify.com/CVE-2026-16624/index.md)","id":"CVE-2026-16624","markdown":"https://insights.sbomify.com/CVE-2026-16624/index.md","name":"CVE-2026-16624","record":{"aliases":["GHSA-4fwh-xxpv-xfm6","GHSA-72qw-2qpq-fg7j"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cal.com scheduling platform","requires_auth":"low_privilege","summary":"Authenticated users can create webhooks for any team by injecting unvalidated team IDs, allowing them to steal sensitive booking data including emails and passwords.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[],"cvss":{"score":9.6,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Cal.com OSS ships lacks authorization on webhook teamId creation, allowing any authenticated user to create a webhook on any team via unvalidated teamId injection, then steal booking data, including fields like organizer/attendee emails and custom responses, and conditionally video-call passwords, by triggering webhook delivery.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"CVE-2026-16624","id":"CVE-2026-16624","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"JasperReports Server: XXE Injection Vulnerability (Unauthenticated)","id":"CVE-2026-16626"},"packages":[],"prev":{"headline":"Create Block Theme \u003c 2.10.0 - Admin+ PHP Code Injection via Pattern Save (Multisite)","id":"CVE-2026-16623"},"products":["Cal.diy"],"published":"2026-07-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-27","vendors":["Cal.com"]},"summary":"Authenticated users can create webhooks for any team by injecting unvalidated team IDs, allowing them to steal sensitive booking data including emails and passwords.","url":"https://insights.sbomify.com/CVE-2026-16624/"}
