CVE-2026-62382: PasswordPusher allows anyone with link to delete shared passwords
CVE-2026-62382 · published 2 months ago
Summary
Versions of PasswordPusher up to 2.9.5 let a user who knows the secret link remove a shared password, even if the original creator tried to block deletion. This happens only when the service is set to accept anonymous pushes, which is the default setting. Upgrade to version 2.9.6 or disable anonymous pushes to stop the problem.
What to do
- Update pglombardo passwordpusher to version 2.9.6 or later.

Original advisory text
PasswordPusher before v2.9.6 Authentication Bypass via Null Comparison
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.
