CVE-2026-49360 — Recce server has unauthenticated SQL execution that allows local file read/write through DuckDB
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 1.1% (30-day exploitation probability)+10
- Technical severity (high)+6
- Automatable exploitation (SSVC)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (DataRecce Recce).
- The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?
CVE-2026-49360 is "Recce server has unauthenticated SQL execution that allows local file read/write through DuckDB", rated High. It affects Recce (DataRecce); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.8 describes technical severity. EPSS 1.08% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
