Description

Impact

What kind of vulnerability is it? Who is impacted?

Account creation restrictions do not work, such as invite only mode, email verification, captcha, and shield verification.

This poses a risk to:

  • Integrity: accounts are immediately verified when the email may not actually be valid.
  • Availability: service may suffer higher DoS risk if there is not active monitoring.

Patches

Has the problem been patched? What versions should users upgrade to?

Patch provided in commit eda3643.

Downgrade to 0.6.13 immediately (20240212-1) or upgrade to 0.7.8 as soon as its available (20240612-1).

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

No.

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.
