{"apiVersion":"1.0","identifier":"CVE-2026-41160","description":"EspoCRM is an open source customer relationship management application. Prior to 9.3.5, a business logic flaw (Broken Access Control) in EspoCRM 9.3.3 allows low-privileged users to pin arbitrary notes without having the required edit permissions for the parent object. Due to a -write first, authorize later- execution flaw in the backend API, even though the server correctly returns a 403 Forbidden error, the targeted note-s pinned status is already persistently modified in the database. The root cause lies in the server-side processing of the POST /api/v1/Note/{id}/pin endpoint. In application/Espo/Tools/Stream/Api/PostNotePin.php, the process() method first calls getNote($id) before calling checkParent($note). This vulnerability is fixed in 9.3.5.","publishedAt":"2026-05-28T17:16:22","lastModifiedAt":null,"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41160","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","epssProbability":0.00292,"riskScore":0.44,"affectedProduct":"EspoCRM","affectedVersions":"<9.3.5","vulnerabilityType":"Package","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41160","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41160","en":"https://www.redsauce.net/en/cves/CVE-2026-41160","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41160","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41160","de":"https://www.redsauce.net/de/cves/CVE-2026-41160","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41160","el":"https://www.redsauce.net/el/cves/CVE-2026-41160"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41160"}}
