CVE-2026-62382

PasswordPusher versions v1.45.11 through v2.9.5 contain an improper authorization vulnerability in the push deletion logic. The ownership check compares @push.user against current_user; for an anonymously created push both values are nil, and Ruby evaluates nil == nil as true, so the check passes and the deletable_by_viewer restriction is never enforced. An attacker who knows only the secret URL can permanently delete an anonymous push even when the creator disabled viewer deletion and even without the passphrase. Only deployments that allow anonymous pushes (the default) are affected. The issue is fixed in v2.9.6.

Summary		(es) Las versiones de PasswordPusher v1.45.11 hasta la v2.9.5 contienen una vulnerabilidad de autorización indebida en la lógica de eliminación de envíos. La verificación de propiedad compara @push.user con current_user; para un envío creado anónimamente, ambos valores son nulos, y Ruby evalúa nil == nil como verdadero, por lo que la verificación pasa y la restricción deletable_by_viewer nunca se aplica. Un atacante que conoce solo la URL secreta puede eliminar permanentemente un envío anónimo incluso cuyo el creador deshabilitó la eliminación por parte del visor e incluso sin la frase de contraseña. Solo las implementaciones que permiten envíos anónimos (el valor predeterminado) se ven afectadas. El problema está solucionado en la v2.9.6.
