CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2026-33479 is a high-severity Code Injection (CWE-94) vulnerability in Wwbn Avideo. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 42th 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — 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-2026-33479 affects WWBN AVideo, an open source video platform, in versions up to and including 26.0. The vulnerability resides in the Gallery plugin's `saveSort.json.php` endpoint, which passes unsanitized user input from the `$_REQUEST['sections']` array values directly into PHP's `eval()` function, enabling code injection (CWE-94). The issue has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H), indicating high severity due to its potential for significant impact.
An attacker can exploit this vulnerability via cross-site request forgery (CSRF), as the endpoint is protected only by `User::isAdmin()` authentication with no CSRF token validation. AVideo's explicit `SameSite=None` configuration on session cookies allows an attacker's malicious page to forge a request from an authenticated admin's browser when the admin visits the attacker-controlled site. This results in unauthenticated remote code execution on the server.
The GitHub security advisory (GHSA-xggw-g9pm-9qhh) and patch commit (087dab8841f8bdb54be184105ef19b47c5698fcb) detail the fix, which sanitizes the input before evaluation to prevent code injection. Security practitioners should update to a patched version beyond 26.0 and consider implementing CSRF protections on admin endpoints as a general best practice.

Vulnerability Data
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the Gallery plugin's `saveSort.json.php` endpoint passes unsanitized user input from `$_REQUEST['sections']` array values directly into PHP's `eval()` function. While the endpoint is gated behind `User::isAdmin()`,…

it has no CSRF token validation. Combined with AVideo's explicit `SameSite=None` session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page. Commit 087dab8841f8bdb54be184105ef19b47c5698fcb contains a patch.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

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.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
