    CVE-2026-30964 (GCVE-0-2026-30964)

    Vulnerability from nvd – Published: 2026-03-10 17:16 – Updated: 2026-03-10 17:57

    Title
    Webauthn Framework: allowed_origins collapses URL-like origins to host-only values, bypassing exact origin validation
    Summary
    web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. Prior to 5.2.4, when allowed_origins is configured, CheckAllowedOrigins reduces URL-like values to their host component and accepts on host match alone. This makes exact origin policies impossible to express: scheme and port differences are silently ignored. This vulnerability is fixed in 5.2.4.

    CVE-2024-39912 (GCVE-0-2024-39912)

    Vulnerability from nvd – Published: 2024-07-15 19:38 – Updated: 2024-08-02 04:33

    Title
    Enumeration of valid usernames in web-auth/webauthn-lib
    Summary
    web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. The ProfileBasedRequestOptionsBuilder method returns allowedCredentials without any credentials if no username was found. When WebAuthn is used as the first or only authentication method, an attacker can enumerate usernames based on the absence of the `allowedCredentials` property in the assertion options response. This allows enumeration of valid or invalid usernames. By knowing which usernames are valid, attackers can focus their efforts on a smaller set of potential targets, increasing the efficiency and likelihood of successful attacks. This issue has been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

    Title
    Webauthn Framework: allowed_origins collapses URL-like origins to host-only values, bypassing exact origin validation
    Summary
    web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. Prior to 5.2.4, when allowed_origins is configured, CheckAllowedOrigins reduces URL-like values to their host component and accepts on host match alone. This makes exact origin policies impossible to express: scheme and port differences are silently ignored. This vulnerability is fixed in 5.2.4.

    CVE-2024-39912 (GCVE-0-2024-39912)

    Vulnerability from cvelistv5 – Published: 2024-07-15 19:38 – Updated: 2024-08-02 04:33
    VLAI
    Title
    Enumeration of valid usernames in web-auth/webauthn-lib
    Summary
    web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. The ProfileBasedRequestOptionsBuilder method returns allowedCredentials without any credentials if no username was found. When WebAuthn is used as the first or only authentication method, an attacker can enumerate usernames based on the absence of the `allowedCredentials` property in the assertion options response. This allows enumeration of valid or invalid usernames. By knowing which usernames are valid, attackers can focus their efforts on a smaller set of potential targets, increasing the efficiency and likelihood of successful attacks. This issue has been addressed in version 4.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
