3DescriptionGitHub Advisory
Blinko is an AI-powered card note-taking project. In versions from 1.8.3 and prior, the plugin file server endpoint uses join() to concatenate paths but does not verify if the final path is within the plugins directory, leading to path traversal. At time of publication, there are no publicly available patches.
AnalysisAI
Blinko versions 1.8.3 and earlier contain a path traversal vulnerability in the plugin file server endpoint that fails to validate whether requested file paths remain within the plugins directory, enabling unauthenticated remote attackers to read arbitrary files. The vulnerability has a CVSS score of 5.3 and currently lacks a publicly available patch.

Vulnerability AssessmentAI
| Risk Assessment | While a formal CVSS score and EPSS probability are not provided, this vulnerability carries significant real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker on the network sends an HTTP GET request to the Blinko plugin endpoint with a crafted path such as '/plugins/../../../../../../etc/passwd' or uses URL-encoded traversal sequences to bypass simple string matching. The vulnerable endpoint joins this attacker-controlled path with the base plugins directory using join() without validation, resolving to an absolute path outside the plugins directory. … |
| Remediation | At the time of publication, no official patch is available from the vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
