rpassword affected by partial password reveal when input is interrupted

Low severity GitHub Reviewed Published Apr 28, 2026 in conradkleinespel/rpassword • Updated May 6, 2026

Package

cargo rpassword (Rust)

Affected versions

<= 7.4.0

Patched versions

7.5.0

Description

rpassword maintainers were made aware of a possible issue with a partial password reveal when input is interrupted.

To quote @squell:

@conradkleinespel I've confirmed this problem with SequoiaPGP, which I think uses rpassword, e.g.:

Suppose we use pkill -9 sq in a different terminal right after the password has been typed in:

$ sq key generate --userid "barf" --with-password
Enter password to protect the key: Killed
$ hello^C

Where the password I typed in is "hello".

This has been fixed in version v7.5.0 and above.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
