Summary

CVE-2026-34732 is a medium-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Wwbn Avideo. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-34732 affects WWBN AVideo, an open source video platform, in versions 26.0 and prior. The vulnerability stems from the CreatePlugin template for list.json.php, which lacks any authentication or authorization checks. Unlike the companion templates add.json.php and delete.json.php that require admin privileges, list.json.php was shipped without such protections. This omission propagates to every plugin generated with the CreatePlugin code generator, creating 21 unauthenticated data listing endpoints that expose sensitive information such as user personally identifiable information (PII), payment transaction logs, IP addresses, user agents, and internal system records. The issue is classified under CWE-306 (Missing Authentication for Critical Function) with a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

Any unauthenticated attacker with network access can exploit this vulnerability due to its low attack complexity and lack of required privileges or user interaction. Exploitation involves sending HTTP requests to the affected list.json.php endpoints, allowing remote retrieval of the sensitive data without credentials. Successful attacks result in low-impact confidentiality breaches, enabling data exposure but without affecting integrity or availability.

The GitHub security advisory (GHSA-g2mg-cgr6-vmv7) details the issue but notes that, at the time of publication on 2026-03-31, no publicly available patches exist for this vulnerability. Security practitioners should monitor the AVideo repository for updates and consider implementing custom authentication checks on the affected endpoints as an interim measure.

Vulnerability Data

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo CreatePlugin template for list.json.php does not include any authentication or authorization check. While the companion templates add.json.php and delete.json.php both require admin privileges, the list.json.php…

template was shipped without this guard. Every plugin that uses the CreatePlugin code generator inherits this omission, resulting in 21 unauthenticated data listing endpoints across the platform. These endpoints expose sensitive data including user PII, payment transaction logs, IP addresses, user agents, and internal system records. At time of publication, there are no publicly available patches.

Mitigating Controls (NIST 800-53 r5) AI

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Access enforcement requires prior authentication before any authorization decision for critical functions.

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.

PR.AA-03 full match
prevents

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-01 partial match
prevents

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-05 partial match
prevents

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

PR.IR-01 partial match
prevents

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.

prevents

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.

mitigates

Mandating authentication for network services and critical functions stops attackers from invoking sensitive operations without credentials, closing gaps where authentication is absent for important capabilities.

prevents

Security engineering principles insist on authentication and authorization for every critical function, eliminating entry points that lack any access control mechanism.

none

Requiring strong authentication and access-privilege enablement for remote connections ensures that critical functions cannot be invoked without proper verification, closing a gap that would otherwise allow unauthenticated use.

none

Mandatory use of access cards, biometrics, or two-factor authentication ensures that critical physical areas cannot be entered without proper authentication.
