Summary

CVE-2026-33041 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 Password Cracking (T1110.002); ranked at the 25th 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 AC-6 (Least Privilege) — see the control section below for these in your framework.

Vulnerability Data

WWBN AVideo is an open source video platform. In versions 25.0 and below, /objects/encryptPass.json.php exposes the application's password hashing algorithm to any unauthenticated user. An attacker can submit arbitrary passwords and receive their hashed equivalents, enabling offline password cracking against…

more

leaked database hashes. If an attacker obtains password hashes from the database (via SQL injection, backup exposure, etc.), they can instantly crack them by comparing against pre-computed hashes from this endpoint. This endpoint eliminates the need for an attacker to reverse-engineer the hashing algorithm. Combined with the weak hash chain (md5+whirlpool+sha1, no salt by default), an attacker with access to database hashes can crack passwords extremely quickly. This issue was fixed in version 26.0.

MITRE ATT&CK Enterprise TechniquesAI

T1110.002 Password Cracking Credential Access
Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained.
Why these techniques?

Endpoint exposure of hashing algorithm directly facilitates offline password cracking (T1110.002) against obtained database hashes.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly blocks unauthenticated access to /objects/encryptPass.json.php, preventing exposure of the password hashing algorithm.

prevent

Ensures the hash-generation endpoint is not reachable by users or processes without an explicit need, eliminating the unauthenticated oracle.

prevent

Disables or restricts non-essential application functions such as the debug/encryptPass endpoint that should never be publicly callable.

PR.AA-05 mostly match
prevents

PR.AA-05 directly enforces least-privilege authorization that blocks most unauthorized disclosures, yet CWE-200 also arises from logging, error messages, and side-channel paths that access controls alone do not address.

PR.DS-10 mostly match
prevents

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 mostly match
prevents

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.

PR.PS-06 mostly match
prevents

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 partial match
prevents

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.

PR.AA-03 partial match
prevents

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.

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

Restricting anonymous or unknown access and encrypting high-value information limits the exposure of sensitive data that would otherwise be obtainable by unauthorized actors.

prevents

Suppressing system details, error specifics, and previous log-on information until successful authentication reduces the information an unauthenticated attacker can gather.

prevents

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.

prevents

Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.

prevents

Secure delivery, protected storage, and confidentiality of allocation records limit exposure of authentication material to unauthorized observers.

prevents

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.
