An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-52838 exists.\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-2026-52838/ (Markdown: https://insights.sbomify.com/CVE-2026-52838/index.md)","id":"CVE-2026-52838","markdown":"https://insights.sbomify.com/CVE-2026-52838/index.md","name":"CVE-2026-52838","record":{"aliases":["GHSA-996f-334j-67g7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Appointment scheduler","requires_auth":"high_privilege","summary":"An authenticated administrator can inject malicious scripts into the disabled booking message, leading to stored XSS for all visitors on the public booking page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":2.6,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Easy!Appointments is a self hosted appointment scheduler. Versions prior to 1.6.0 allow administrators to define a custom \"booking disabled\" message through the booking settings page. That value is stored in the `disable_booking_message` setting via a rich-text editor and later passed directly to the public `booking_message` view without escaping or sanitization. An authenticated administrator can store HTML or JavaScript in this field, enable disabled-booking mode, and trigger stored XSS in every unauthenticated visitor who opens the public booking page. Version 1.6.0 fixes the issue.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Easy!Appointments disable_booking_message rendered as raw HTML on public booking page — Stored XSS","id":"CVE-2026-52838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Easy!Appointments appointments/store and appointments/update allow cross-provider appointment injection — Authorization Bypass","id":"CVE-2026-52839"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.5.2"],"package":"alextselegidis/easyappointments","purl":null,"source":"GHSA-996f-334j-67g7"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.5.2"],"package":"alextselegidis/easyappointments","purl":"pkg:composer/alextselegidis/easyappointments","source":"GHSA-996f-334j-67g7"}],"prev":{"headline":"Easy!Appointments has unauthenticated customer PII disclosure on booking reschedule page","id":"CVE-2026-52837"},"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["alextselegidis"]},"summary":"An authenticated administrator can inject malicious scripts into the disabled booking message, leading to stored XSS for all visitors on the public booking page.","url":"https://insights.sbomify.com/CVE-2026-52838/"}
