Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Organizations should immediately upgrade to a patched version of WWBN AVideo that includes the fix for this vulnerability. If upgrading is not immediately possible, administrators should implement access controls at the web server or network level to restrict access to the `plugin/AD_Server/reports.json.php` endpoint to trusted administrative IP addresses only. Additionally, auditing and monitoring access logs for unusual or unauthorized requests to this endpoint can help detect exploitation attempts. Developers maintaining custom forks or deployments should verify that all API endpoints enforce consistent authorization checks, especially for administrative data. Regular security reviews and automated testing for missing authorization vulnerabilities (CWE-862) should be integrated into the development lifecycle to prevent similar issues. Finally, organizations should review their data exposure policies and ensure that sensitive analytics data is only accessible to authorized personnel.

Description

CVE-2026-33685 is a medium severity vulnerability in WWBN AVideo versions up to 26.0 where the JSON API endpoint for ad campaign reports lacks any authentication or authorization checks. This allows unauthenticated attackers to access sensitive ad analytics data including video titles, user channel names, user IDs, ad campaign names, and impression/click counts. While the HTML and CSV report endpoints enforce admin checks, the JSON endpoint was left unprotected. The vulnerability does not allow modification of data or system compromise but leaks confidential business and user information. A patch has been committed to fix this missing authorization issue. Organizations using affected versions should update promptly to prevent unauthorized data disclosure.

Impact

The primary impact of this vulnerability is unauthorized disclosure of sensitive advertising analytics data. Organizations using affected versions of WWBN AVideo risk leakage of business intelligence such as ad campaign performance metrics, user channel information, and video metadata. This information could be leveraged by competitors or malicious actors for profiling, reconnaissance, or crafting targeted social engineering attacks. Although the vulnerability does not allow modification or disruption of services, the confidentiality breach can undermine user trust and violate privacy policies or contractual obligations. For organizations relying on AVideo for monetization or user engagement analytics, this data exposure could result in financial and reputational damage. Since exploitation requires no authentication and no user interaction, the attack surface is broad, increasing the likelihood of opportunistic data harvesting.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #4OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
