CVE-2026-33867 is a critical-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Wwbn Avideo. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 5th 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 SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-33867 affects WWBN AVideo, an open source video platform, in versions up to and including 26.0. The vulnerability involves the plaintext storage of passwords used to protect individual videos in the database, without any hashing, salting, or encryption applied. This issue, classified under CWE-312 (Cleartext Storage of Sensitive Information), has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with network accessibility and no privileges required.
An attacker who gains read access to the AVideo database—through methods such as SQL injection, acquisition of a database backup, or exploitation of misconfigured access controls—can directly retrieve all video passwords in cleartext. No authentication or user interaction is needed beyond obtaining database read privileges, allowing unauthorized access to otherwise password-protected video content across the platform.
Mitigation is available via a patch in commit f2d68d2adbf73588ea61be2b781d93120a819e36 on the AVideo GitHub repository. The GitHub Security Advisory GHSA-363v-5rh8-23wg provides further details on the issue and remediation steps. Administrators should update to a patched version and review database access controls to prevent unauthorized reads.

SC-28 requires cryptographic or equivalent protection of sensitive data at rest, directly stopping cleartext storage in accessible resources.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.
Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.
Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.
Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.
Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.
When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.
By insisting that any retained test copies be stored securely and only for testing, the control reduces the likelihood that clear-text operational data will persist on disk or in backups.
