Associated Vulnerability

Title: PasswordPusher before v2.9.6 Authentication Bypass via Null Comparison (CVE-2026-62382)
Description: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.

Description

PasswordPusher v1.45.11 through v2.9.5 allows unauthenticated deletion of anonymous pushes due to a nil==nil ownership-check bypass (CWE-863). The deletion guard evaluates (@push.user == current_user) || @push.deletable_by_viewer. For anonymous pushes, @push.user is nil; for unauthenticated requests, current_user is nil. Ruby evaluates nil==nil as true, so the ownership check passes and the deletable_by_viewer=false restriction is completely bypassed. Anyone who knows the secret URL token can permanently expire an anonymous push without any credentials.
