CVE-2026-67196
Perspective 5.0.0 XSS via Debug Plugin innerHTML Interpolation
Description
Perspective 5.0.0 contains a cross-site scripting vulnerability in the built-in Debug plugin that allows attackers to inject arbitrary HTML and JavaScript by writing table cell values containing unescaped HTML markup, which are interpolated directly into innerHTML during CSV serialization rendering. Attackers can craft table rows with payloads such as unquoted attribute injections containing event handler attributes that bypass RFC 4180 quoting, since angle brackets and event handler attributes are never escaped before assignment, causing malicious scripts to execute in the embedding page's origin.

Action Type Old Value New Value Added Translation Title: perspective de perspective-dev, Description: Perspective 5.0.0 contiene una vulnerabilidad de cross-site scripting en el plugin Debug incorporado que permite a los atacantes inyectar HTML y JavaScript arbitrarios escribiendo valores de celdas de tabla que contienen marcado HTML sin escapar, los cuales se interpolan directamente en innerHTML durante la renderización de la serialización CSV. Los atacantes pueden crear filas de tabla con cargas útiles como inyecciones de atributos sin comillas que contienen atributos de gestor de eventos que eluden el entrecomillado de RFC 4180, ya que los corchetes angulares y los atributos de gestor de eventos nunca se escapan antes de la asignación, provocando que los scripts maliciosos se ejecuten en el origen de la página incrustada. -
