Burrito is a Terraform Automation Collaboration Software (TACoS) Kubernetes operator. Prior to 0.13.0, POST /api/webhook accepts unsigned GitHub and GitLab events when a TerraformRepository's credentials omit webhookSecret or set it to an empty value, including credentials configured for git authentication and polling. Credential.WebhookSecret is optional, and go-playground/webhooks skips signature or token verification when the secret is empty. Anyone who can reach burrito-server's 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 against that pull request. Pairing a real, existing pull request number with an unrelated existing branch in the same repository can therefore cause an unauthorized terraform plan for affected layers using the operator's stored git and cloud credentials. Code analysis also indicates that the resulting plan can be posted to the real pull request's comment thread, exposing and misattributing another branch's infrastructure changes. Auto-apply is disabled for these temporary layers, so this vulnerability alone cannot force a terraform apply; plan-time provider and data-source code execution depends on the selected branch's contents. This issue is fixed in version 0.13.0.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Exploitation none (no CISA value, KEV listing or exploit code on record) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). EchelonGraph holds no SSVC assessment of this CVE from CISA: none of these inputs is from Vulnrichment. EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse". CISA's decision table

BOD 26-04 (CISA's remediation timeline, Table 1)14 days if the affected system is publicly exposed; Fix on system upgrade if it is not.

In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it
