What is CVE-2026-49360?
CVE-2026-49360 is a high-severity SQL injection vulnerability in DataRecce recce, published on 21 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Recce is a data-validation toolkit for enhanced dbt (data build tool) PR review. Prior to version 1.50.0, OSS server deployments that expose the server to an untrusted network without authentication are vulnerable to unauthenticated SQL execution through the query run API. When Recce is configured with a DuckDB-backed project, an attacker can use DuckDB filesystem primitives to read and write files accessible to the Recce server process. The impact depends on how Recce is deployed, but may include disclosure of local files, tampering with Recce/dbt artifacts, modification of browser-served static files leading to stored XSS, and modification of application files if those paths are writable. If Recce is run as root, file access occurs with root privileges inside that host or container. This issue has been patched in Recce `v1.50.0`. Users should upgrade to Recce `v1.50.0` or later. The patch restricts unsafe file read/write behavior for DuckDB-backed query execution and hardens the affected query path. Other warehouse adapters have also been reviewed for similar exposure. Users who cannot upgrade immediately should avoid exposing `recce server` to the public internet or any untrusted network. Recommended mitigations include enabling authentication or placing Recce behind an authenticated reverse proxy/VPN, running Recce as a non-root user, using a read-only application filesystem where possible, and ensuring that sensitive files or credentials are not available to the Recce process.
Weakness: CWE-73
