Description
Bugsink’s issue list supports bulk actions such as resolving or muting selected issues. In affected versions, the issue list view authorizes access through the project in the URL, but applies the requested bulk action to the submitted issue IDs without also requiring those issues to belong to that project.
This is a project-boundary authorization issue: a logged-in user with access to one project can change the state of an issue in another project. However, the issue is mitigated by two factors. First, the attacker needs to already know a valid target issue UUID; there is no issue enumeration path here, and guessing UUIDs is not practical. Second, Bugsink is commonly self-hosted within a single trust domain, and Hosted Bugsink gives each tenant a separate Bugsink instance, so cross-project access does not normally imply cross-tenant access.
This has been fixed by requiring bulk issue actions to operate only on issues belonging to the authorized project.
Impact
Low-severity cross-project issue state modification, requiring authentication and prior knowledge of a valid issue UUID.
The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the integrity of the data.
Limited exploitation activity has been observed. Close monitoring and planned remediation are recommended.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
