CVE-2026-47357: Tenable Terrascan Server Side Request Forgery (CVSS 9.2)

Terrascan v1.18.3 and prior are vulnerable to Server-Side Request Forgery (SSRF) via external URL resolution in uploaded IaC templates when running in server mode. When Terrascan parses uploaded ARM templates or CloudFormation templates, it resolves external URLs referenced within those templates via hashicorp/go-getter with all default detectors enabled, including FileDetector. An unauthenticated remote attacker can upload an ARM template containing a templateLink.uri or parametersLink.uri field, or a CloudFormation template containing an AWS::CloudFormation::Stack TemplateURL field, pointing to an attacker-controlled URL. Terrascan will fetch the attacker-controlled URL server-side. Unlike SSRF via the remote scan endpoint, file:// URLs are directly usable without requiring an X-Terraform-Get redirect, enabling local file read. This affects deployments running terrascan in server mode (terrascan server), which binds to 0.0.0.0 with no authentication. Note: Terrascan was archived in August 2023 and no patch will be released.

Terrascan v1.18.3 and prior are vulnerable to Server-Side Request Forgery (SSRF) via the webhook_url parameter in the file scan endpoint (POST /v1/{iac}/{iacVersion}/{cloud}/local/file/scan) when running in server mode. An unauthenticated remote attacker can supply an arbitrary URL as the webhook_url multipart form parameter. After scanning the uploaded file, Terrascan sends an HTTP POST request to the attacker-controlled URL containing the full scan results as a JSON body, with the attacker-supplied webhook_token forwarded as a Bearer token in the Authorization header. The retryable HTTP client retries up to 10 times on failure. This affects deployments running terrascan in server mode (terrascan server), which binds to 0.0.0.0 with no authentication. Note: Terrascan was archived in August 2023 and no patch will be released.

This vulnerability allows an attacker to create a junction, enabling the deletion of arbitrary files with SYSTEM privileges. As a result, this condition potentially facilitates arbitrary code execution, whereby an attacker may exploit the vulnerability to execute malicious code with elevated SYSTEM privileges.

Flowise through 2.2.7 fails to sanitize path segments in the document-store loader endpoint, allowing unauthenticated attackers to write files outside the storage directory. Attackers can use parent-directory sequences to escape the storage directory and overwrite application files loaded at boot for remote code execution.

Metabase is an open-source business intelligence and embedded analytics tool. From 1.54.0 until 1.54.24, 1.55.24, 1.56.25, 1.57.19, 1.58.14, 1.59.10, and 1.60.4, a Metabase user with permission to add or edit a database connection can achieve remote code execution on the Metabase server by configuring a Snowflake connection to an attacker-controlled server, because a flaw in the Snowflake JDBC driver can write arbitrary files anywhere on the Metabase host, including replacing one of Metabase's own database driver files that later executes inside the Metabase process. This issue is fixed in versions 1.54.24, 1.55.24, 1.56.25, 1.57.19, 1.58.14, 1.59.10, and 1.60.4.

IBM DataStage on Cloud Pak for Data 5.4.0.0 IBM DataStage could allow a remote authenticated attacker to perform an arbitrary file write due to improper validation of file paths.
