CVE-2026-33761 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) 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-3 (Access Enforcement) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Vulnerability Data
WWBN AVideo is an open source video platform. In versions up to and including 26.0, three `list.json.php` endpoints in the Scheduler plugin lack any authentication check, while every other endpoint in the same plugin directories (`add.json.php`, `delete.json.php`, `index.php`) requires `User::isAdmin()`.…

An unauthenticated attacker can retrieve all scheduled tasks (including internal callback URLs and parameters), admin-composed email messages, and user-to-email targeting mappings by sending simple GET requests. Commit 83390ab1fa8dca2de3f8fa76116a126428405431 contains a patch.

Why these techniques?
Missing authorization on public Scheduler plugin endpoints directly enables unauthenticated information disclosure from a web application, mapping to exploitation of public-facing apps.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization checks on all Scheduler plugin endpoints before returning sensitive task, callback URL, and email data, which the CVE shows were completely absent on the list.json.php paths.
Requires identification and authentication of users prior to any access, eliminating the unauthenticated GET requests that exposed internal scheduler and email-mapping information.
Ensures only the minimum necessary privileges (e.g., isAdmin()) are granted, directly addressing the inconsistent and missing privilege checks described in the Scheduler plugin.

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.
Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.
PR.DS-10 mostly prevents CWE-200 by directly eliminating unauthorized access to sensitive data-in-use, yet only partially addresses the weakness because CWE-200 spans many other exposure vectors outside runtime protection.
PR.IR-01's segmentation/zero-trust controls largely eliminate network-level unauthorized access paths that enable exposure, yet CWE-200 spans many additional vectors (API responses, logs, app logic) that network controls alone cannot close.
Secure SDLC practices catch most exposure flaws via design, testing and release controls, yet CWE-200 spans runtime/config issues a single development outcome cannot fully close.
PR.AA-01 supplies proper credential lifecycle controls that reduce unauthorized access paths, yet leaves many other exposure vectors (error messages, logging, side channels, etc.) unaddressed.
Authentication verifies actor identity and is a prerequisite for access decisions, yet addresses only one facet of the broad set of exposure vectors in CWE-200.

Restricting anonymous or unknown access and encrypting high-value information limits the exposure of sensitive data that would otherwise be obtainable by unauthorized actors.
Suppressing system details, error specifics, and previous log-on information until successful authentication reduces the information an unauthenticated attacker can gather.
By requiring owners to assign sensitivity labels and corresponding handling rules, the control ensures that information is not left unmarked and therefore reduces the chance that sensitive data will be exposed to unauthorized actors.
Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.
Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.
Requiring defined procedures, assigned roles, and technical/organizational measures for handling PII reduces the chance that sensitive personal data will be exposed to unauthorized actors through inadequate handling or missing safeguards.
