CVE-2026-30244
Published: 06 March 2026
Summary
CVE-2026-30244 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor (CWE-200) vulnerability in Plane Plane. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 9.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).
Deeper analysis
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. Additional details are available in the release notes at https://github.com/makeplane/plane/releases/tag/v1.2.2 and the GitHub security advisory at https://github.com/makeplane/plane/security/advisories/GHSA-87x4-j8vh-p5qf.

Directly requires identification and explicit authorization of permitted actions without identification or authentication, preventing unauthenticated access to sensitive workspace member endpoints.
Mandates enforcement of approved authorizations for logical access to information and resources, addressing the failure of permission classes to restrict anonymous access to protected data.
Requires establishment and documentation of secure configuration settings for system components, such as Django REST Framework permissions, to mitigate misconfigurations exposing sensitive information.
