Lifecycle Timeline

Bernd Bestel grocy v4.6.0 was discovered to contain a SQL injection vulnerability in the product-group parameter at /stockreports/spendings. This vulnerability allows attackers to access sensitive database information via a crafted SQL statement.
AnalysisAI
SQL injection in Bernd Bestel grocy v4.6.0 lets remote attackers extract sensitive database contents by injecting a crafted SQL statement through the product-group parameter of the /stockreports/spendings endpoint. The CVSS 3.1 base score is 9.8 (AV:N/AC:L/PR:N/UI:N) and SSVC rates technical impact as total with automatable exploitation, though EPSS remains low at 0.15%; publicly available exploit code exists via a published gist, but there is no public exploit identified as actively exploited (not in CISA KEV).
Technical ContextAI
grocy is a self-hosted, web-based ERP/groceries-and-household management application (PHP with an SQLite backend) commonly run in home-lab and small-office contexts. The flaw is a classic CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) issue: the product-group parameter consumed by the stock spendings report at /stockreports/spendings is concatenated into a SQL query without proper parameterization or sanitization, allowing an attacker's input to alter query structure. The provided CPE string (cpe:2.3:a:n/a:n/a:*) is a placeholder and does not identify the product precisely, so the affected component is derived from the description rather than structured NVD CPE data.
RemediationAI
No vendor-released patch identified at time of analysis - no fixed version or upstream commit is present in the provided data, so monitor the grocy project (github.com/grocy/grocy) and its release notes for a version superseding 4.6.0 and upgrade as soon as one is published. As compensating controls, restrict network access to the grocy instance (it is designed for private/home-lab use, so place it behind a VPN or firewall and do not expose it to the internet), require authentication and limit the spendings/stockreports functionality to trusted users, and place a WAF or reverse-proxy rule in front of the /stockreports/spendings endpoint to filter SQL metacharacters in the product-group parameter - noting that WAF filtering is a stopgap that can be bypassed and may break legitimate group names containing special characters. Review the referenced PoC gist to build detection signatures for the specific injection pattern.
