Prior to version 0.28.0, a stored cross-site scripting (XSS) vulnerability exists in the description_html field of Plane. This flaw allows an attacker to inject malicious JavaScript code that is stored and later executed in other users\u2019 browsers. The description_html field is not properly sanitized or escaped. An attacker can submit crafted JavaScript payloads that are saved in the application\u2019s database. When another user views the affected content, the injected code executes in their browser, running in the application\u2019s context and bypassing standard security protections. Successful exploitation can lead to session hijacking, theft of sensitive information, or forced redirection to malicious sites. The vulnerability can also be chained with CSRF attacks to perform unauthorized actions, or leveraged to distribute malware and exploit additional browser vulnerabilities. This issue has been patched in version 0.28.0."}, {"lang": "es", "value": "Plane es un software de gesti\u00f3n de proyectos de c\u00f3digo abierto. Antes de la versi\u00f3n 0.28.0, exist\u00eda una vulnerabilidad de cross site scripting (XSS) almacenado en el campo description_html de Plane. Esta falla permite a un atacante inyectar c\u00f3digo JavaScript malicioso que se almacena y posteriormente se ejecuta en los navegadores de otros usuarios. El campo description_html no se depura ni escapa correctamente. Un atacante puede enviar payloads de JavaScript manipuladas que se guardan en la base de datos de la aplicaci\u00f3n. Cuando otro usuario visualiza el contenido afectado, el c\u00f3digo inyectado se ejecuta en su navegador, ejecut\u00e1ndose en el contexto de la aplicaci\u00f3n y evadiendo las protecciones de seguridad est\u00e1ndar. Una explotaci\u00f3n exitosa puede provocar el secuestro de sesi\u00f3n, el robo de informaci\u00f3n confidencial o la redirecci\u00f3n forzada a sitios maliciosos.
