Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Enforces rules governing access to the system and its data from external systems based on established trust relationships.
This control requires verifying that a sharing partner's access authorizations match the information's restrictions before sharing occurs.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Public-facing web app info disclosure vuln directly enables unauthenticated exploitation (T1190) and facilitates remote enumeration of email accounts/roles/IDs (T1087.003).
NVD Description
Plane is an an open-source project management tool. Prior to version 1.2.2, unauthenticated attackers can enumerate workspace members and extract sensitive information including email addresses, user roles, and internal identifiers. The vulnerability stems from Django REST Framework permission classes being…

incorrectly configured to allow anonymous access to protected endpoints. This issue has been patched in version 1.2.2.
Deeper analysisAI
CVE-2026-30244 is an information disclosure vulnerability affecting Plane, an open-source project management tool built on Django REST Framework. In versions prior to 1.2.2, permission classes were incorrectly configured on certain endpoints, granting unauthenticated anonymous access to data that should have been protected. This allows attackers to enumerate workspace members and extract sensitive details, including email addresses, user roles, and internal identifiers. The flaw carries 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) and maps to CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) and CWE-284 (Improper Access Control).
Unauthenticated remote attackers can exploit this vulnerability with low complexity and no user interaction or privileges required. By sending requests to the exposed endpoints, they can systematically retrieve lists of workspace members along with their associated sensitive information, enabling broad reconnaissance on organizational personnel without authentication.
The vulnerability has been patched in Plane version 1.2.2 by correcting the permission configurations. Administrators should upgrade to this version or later to mitigate the issue.
