Prior to version 2.2.2, the `LinkSharing.ReadAll()` method allows link share authenticated users to list all link shares for a project, including their secret hashes. While `LinkSharing.CanRead()` correctly blocks link share users from reading individual shares via `ReadOne`, the `ReadAllWeb` handler bypasses this check by never calling `CanRead()`. An attacker with a read-only link share can retrieve hashes for write or admin link shares on the same project and authenticate with them, escalating to full admin access. Version 2.2.2 patches the issue."},{"lang":"es","value":"Vikunja es una plataforma de gestión de tareas de código abierto autoalojada. Antes de la versión 2.2.2, el método `LinkSharing.ReadAll()` permite a los usuarios autenticados con un enlace compartido listar todos los enlaces compartidos de un proyecto, incluyendo sus hashes secretos. Si bien `LinkSharing.CanRead()` bloquea correctamente a los usuarios de enlaces compartidos de leer enlaces compartidos individuales a través de `ReadOne`, el gestor `ReadAllWeb` omite esta verificación al no llamar nunca a `CanRead()`. Un atacante con un enlace compartido de solo lectura puede recuperar hashes de enlaces compartidos de escritura o de administrador en el mismo proyecto y autenticarse con ellos, escalando a acceso de administrador completo. La versión 2.2.2 corrige el problema."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-285"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:vikunja:vikunja:*:*:*:*:*:*:*:*","versionEndExcluding":"2.2.2","matchCriteriaId":"79DC3F0A-11CE-4DAA-884D-F285B5D344DD"}]}]}],"references":[{"url":"https://github.com/go-vikunja/vikunja/commit/9efe1fadba817923c7c7f5953c3e9e9c5683bbf3","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-8hp8-9fhr-pfm9","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://vikunja.io/changelog/vikunja-v2.2.2-was-released","source":"security-advisories@github.com","tags":["Release Notes"]}]}}]}
