An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-52841 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- alextselegidis/easyappointments (Packagist): affected all versions up to 1.5.2; no fix listed\n- alextselegidis/easyappointments (Packagist): affected all versions up to 1.5.2; no fix listed\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-2026-52841/ (Markdown: https://insights.sbomify.com/CVE-2026-52841/index.md)","id":"CVE-2026-52841","markdown":"https://insights.sbomify.com/CVE-2026-52841/index.md","name":"CVE-2026-52841","record":{"aliases":["GHSA-8hm4-r66f-29wr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Appointment scheduler","requires_auth":"high_privilege","summary":"Logged-in users can rebind other users' Google OAuth providers to their own accounts, gaining unauthorized access to peer appointment data.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Easy!Appointments is a self hosted appointment scheduler. In versions prior to 1.6.0, `Google::oauth` at `application/controllers/Google.php:278` stores its URL-supplied `provider_id` in the session, and `oauth_callback` saves the issued Google OAuth token against that row without checking the caller owns the provider. Any logged-in backend user (admin, provider, or secretary) rebinds a peer provider's Google sync to a Google account they control. The peer's appointments then sync into the attacker's calendar with each customer's name and email attached as attendee data. Version 1.6.0 patches the issue.","ecosystems":["Packagist"],"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":"Easy!Appointments: Authorization bypass in Google OAuth provider binding lets any backend user rebind a peer provider's Google sync","id":"CVE-2026-52841","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Lightpanda:URL parser misidentifies page origin for URLs containing @ in the path - Same-Origin Policy bypass","id":"CVE-2026-52842"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.5.2"],"package":"alextselegidis/easyappointments","purl":null,"source":"GHSA-8hm4-r66f-29wr"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.5.2"],"package":"alextselegidis/easyappointments","purl":"pkg:composer/alextselegidis/easyappointments","source":"GHSA-8hm4-r66f-29wr"}],"prev":{"headline":"Easy!Appointments has server-side request forgery in CalDAV connection test that exposes the deployment's internal network","id":"CVE-2026-52840"},"products":["easyappointments"],"published":"2026-07-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["alextselegidis"]},"summary":"Logged-in users can rebind other users' Google OAuth providers to their own accounts, gaining unauthorized access to peer appointment data.","url":"https://insights.sbomify.com/CVE-2026-52841/"}
