CVE-2026-73313

XenForo versions before 2.3.13 contain an MFA bypass vulnerability in the passkey TFA provider . During the WebAuthn assertion step, the passkey verification path performs a global credential lookup without validating that the matched credential belongs to the user whose login is pending. This al...

XenForo before 2.3.13 contains a multi-factor authentication bypass vulnerability in the passkey TFA provider that allows an authenticated attacker to complete login as another user by submitting their own registered passkey credential during the WebAuthn assertion step. The passkey verification...

BIT-GRAFANA-2026-12704 SAML assertion replay via skipped InResponseTo validation

When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and ga...

CVE-2026-78623: Improper Neutralization of Special Elements used in an SQL Command

The Okta Access Gateway does not sanitize SAML assertion values before interpolating them into database queries in the advanced mode datastore configuration. The unsanitized values are substituted directly into the query string prior to preparation, resulting in unintended SQL execution against t...
