CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-1909 is a critical-severity Authentication Bypass Using an Alternate Path or Channel (CWE-288) vulnerability in Buddyboss Buddyboss Platform. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Stealth (T1211); ranked in the top 49% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-25 (Reference Monitor) and AC-3 (Access Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The BuddyBoss Platform Pro plugin for WordPress is affected by an authentication bypass vulnerability in versions up to and including 2.7.01. The flaw arises from insufficient verification of the supplied user identity during Apple OAuth authentication requests through the plugin, which is tracked under CWE-288.
Unauthenticated attackers can exploit the issue over the network to log in as any existing user account on the site, including administrators, as long as they possess access to the associated email address. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting its critical impact on confidentiality, integrity, and availability without requiring user interaction or privileges.
Advisories from the vendor and Wordfence recommend updating to a patched release; the referenced BuddyBoss changelogs indicate that version 2.7.10 and later address the OAuth verification gap. The EPSS score remains low and unchanged at 0.0103 with no observed rise after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.
Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.
Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.
Controls all external and key internal interfaces, reducing the chance of unauthenticated alternate channels.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requiring authentication on every channel and path directly eliminates alternate-path bypasses.
Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.
Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.

Security testing can detect alternate-path bypasses but does not prevent them in production.
A.8.3's core (access restriction per policies, config mechanisms, identity/group controls, isolation, dynamic techniques requiring auth/credentials) directly stops exploitation of alternate unauthenticated paths for most instances; the bounded remainder is non-access-channel cases (e.g. pure logic errors in alternate-path checks) or pre-auth bypasses outside its enforcement scope.
A.8.5 mandates strong, multi-factor, alternate-path-resistant authentication techniques plus hardened log-on procedures that directly block unauthenticated alternate channels for most cases (e.g. no bypass via weak paths, sniffing, or incomplete checks); the bounded remainder is non-standard or environment-specific alternate channels outside the clause's listed protections.
Access rights provisioning and review prevent bypass via unmonitored or alternate channels.
Privileged access rights control reduces risk of bypass through elevated or alternate paths.
Secure coding practices help avoid bypass vulnerabilities but do not address deployed instances.
