Title

Plane IDOR: Cross-Project Issue Date Modification via Bulk Update Endpoint

Summary

Plane is an an open-source project management tool. Prior to 1.3.0, the IssueBulkUpdateDateEndpoint allows a project member (ADMIN or MEMBER) to modify the start_date and target_date of ANY issue across the entire Plane instance, regardless of workspace or project membership. The endpoint fetches issues by ID without filtering by workspace or project, enabling cross-boundary data modification. This vulnerability is fixed in 1.3.0.

Severity

6.5 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
