CVE-2026-62382

PasswordPusher before v2.9.6 Authentication Bypass via Null Comparison

Published Aug 22, 2026 CVSS 4.0 · 6.9 Medium EPSS 1.2% KEV · Not listed
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.
