Cross-workspace authorization bypass in Plane (makeplane) prior to version 1.3.1 allows any authenticated user of one workspace to read, copy, delete, and overwrite file assets belonging to other workspaces on the same instance. The flaw stems from missing membership checks on V2 asset endpoints and is fixed in v1.3.1; no public exploit identified at time of analysis.
Server-Side Request Forgery (SSRF) in Makeplane Plane (versions 0.28.0 to before 1.3.0) allows authenticated attackers with low privileges to perform full-read SSRF attacks against internal network resources. The vulnerability exists because incomplete remediation of a previous SSRF issue (GHSA-jcc6-f9v6-f7jw) left the favicon fetch path vulnerable to redirect-based attacks. When an attacker supplies an HTML page containing a link tag with an href redirecting to a private IP address via the 'Add link' feature, the fetch_and_encode_favicon() function follows redirects without validation, enabling unauthorized access to internal resources. Requires authenticated access; no public exploit identified at time of analysis.
Plane project management tool versions prior to 1.3.0 allow authenticated project members to modify issue dates across workspace and project boundaries via the IssueBulkUpdateDateEndpoint, which lacks proper authorization filtering. An attacker with ADMIN or MEMBER role in any project can arbitrarily change start_date and target_date fields on issues they have no legitimate access to, enabling data integrity violations across the entire Plane instance. EPSS score of 6.5 reflects moderate real-world risk for this privilege escalation, with no public exploit code or active exploitation confirmed at time of analysis.
Unauthenticated attackers can enumerate workspace members and harvest sensitive information including email addresses, user roles, and internal identifiers from Plane prior to version 1.2.2 due to misconfigured Django REST Framework permissions. The vulnerability requires no authentication or user interaction and allows remote attackers to directly access protected endpoints over the network. No patch is currently available for affected Golang and Django deployments.
Plane is an an open-source project management tool. [CVSS 8.5 HIGH]
Plane versions before 1.2.2 contain a server-side request forgery vulnerability in the "Add Link" feature that allows authenticated users to send arbitrary GET requests to internal networks and retrieve full response bodies. An attacker with basic user privileges can exploit this to steal sensitive data from internal services and cloud metadata endpoints. No patch is currently available.
Broken object-level authorization (IDOR) in Plane through 1.4.2 allows authenticated attackers to post comments on arbitrary issues across any workspace by supplying a manipulated issue_id to the public deploy-board comment endpoint. The endpoint at apps/api/plane/space/views/issue.py (lines 258-275) performs no validation that the supplied issue belongs to the project associated with the deploy board, enabling cross-workspace data pollution. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis, and the CVSS 4.0 base score is 5.3 (Medium).
Cross-tenant authorization bypass in Plane's asset-management API allows any authenticated workspace member to read, delete, or duplicate file assets belonging to an entirely different workspace on the same instance, affecting all releases through 1.3.0. The API endpoints accept a workspace slug and asset ID as path parameters but perform no membership verification against the requesting user's session, returning presigned file URLs and permitting destructive operations across tenant boundaries. No public exploit has been identified at time of analysis, and EPSS exploitation probability stands at 0.15% (5th percentile), though the attack is mechanically straightforward for any authenticated user who can enumerate workspace slugs and asset IDs.
Stored cross-site scripting in Plane CE 1.3.1 allows an authenticated low-privileged project member to inject arbitrary HTML and JavaScript via the `description_html` field through the API v1 intake endpoint, with payloads persisting in the database and executing in the browsers of any user who views the affected intake item. The CVSS 4.0 vector rates confidentiality impact on the vulnerable system as High (VC:H), reflecting the realistic threat of session token exfiltration from higher-privileged users such as project administrators. No active exploitation has been confirmed and no public exploit code has been identified at time of analysis.
ORM Field Reference Injection in Plane versions 1.3.0 and below enables any authenticated workspace MEMBER to exfiltrate sensitive data - including bcrypt password hashes, API tokens, and user email addresses - via a single crafted GET request. The SavedAnalyticEndpoint omits the field allowlist validation present in the regular AnalyticsEndpoint, passing the user-supplied segment parameter directly into Django F() expressions, which then traverse foreign-key relationships and return referenced field values in the JSON response. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the attack is trivially reconstructable from the public GHSA-93x3-ghh7-72j3 advisory and the exfiltrated data directly enables secondary attacks.
Plane project management tool versions prior to 1.3.0 leak user email addresses in authentication error URLs, transmitting personally identifiable information via unencrypted GET query parameters. The vulnerability requires high-privilege access and user interaction to trigger, exposing email disclosure with low confidentiality impact and no integrity or availability consequences. This is a low-severity information disclosure issue with CVSS 2.0, actively patched in version 1.3.0.
Plane prior to version 1.2.2 allows authenticated users to modify project assets across any workspace by directly referencing asset IDs, as the asset lookup fails to verify workspace and project ownership. An attacker with guest-level credentials can enumerate asset UUIDs and alter asset attributes and upload status without authorization. The vulnerability has been patched in version 1.2.2.
