CVE-2026-88817
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
An authenticated, non-guest user of Curiosity Workspace could enroll themselves as an administrator and member of an existing access group without an invitation or approval. It did not grant application-wide administrator privileges, and the vulnerability could not be used to obtain root access to the application or its underlying host.
Risk Assessment
An attacker could gain unauthorized access to resources of an existing access group, potentially leading to unauthorized access to data or functions. The risk is limited because application-wide administrator privileges and root access were not obtained.
Recommendation
Review and restrict the ability to self-enroll into access groups and enforce an invitation or approval requirement. Review access group membership to detect unauthorized changes.

A vulnerability in the Burrito Kubernetes operator (Terraform Automation Collaboration Software) prior to 0.13.0 allows the POST /api/webhook endpoint to accept unsigned GitHub and GitLab events when a TerraformRepository's credentials omit webhookSecret or set it to an empty value. Anyone who can reach the burrito-server endpoint and knows a tracked repository's URL can forge events to create or delete TerraformPullRequest custom resources with attacker-chosen Branch, Base, and ID fields. For GitHub pull_request events, the controller fetches changed files using the real pull request number but does not cross-check the payload's branch, potentially causing an unauthorized terraform plan using the operator's stored git and cloud credentials.
