Technical description

Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 2.1.1, several read capabilities interpolate caller-controlled values into DQL without sufficient validation or escaping. The src/capabilities/find-monitored-entity-by-name.ts capability embeds entityNames in string searches, src/capabilities/list-problems.ts, src/capabilities/list-vulnerabilities.ts, and src/capabilities/list-exceptions.ts embed timeframe values, and src/capabilities/get-events-for-cluster.ts embeds timeframe, clusterId, and kubernetesEntityId. Crafted values can close string literals, append pipeline stages, or comment out the remaining intended query, allowing callers to bypass field selection, time-window, and result-display limits in tools marked readOnlyHint. The issue does not grant data access beyond the configured token's existing execute_dql capability, but it breaks the narrower auto-approved tool contract. This issue is fixed in version 2.1.1.

———An unauthenticated SQL injection can occur on the front end of any site that uses craft.search to perform a search, allowing stacked query execution and enabling escalation to an administrator. Note that this only affects MySQL/MariaDB. Impact * SQL injection — The attribute parameter is concatenated into the query unsanitized, and because PDO runs with emulated prepares, stacked statements execute. This gives unauthenticated read and write access to the application database. * Privilege escalation to administrator — The write primitive was used to set the admin flag on user ID 1 in the users table, confirmed by reading the value back. Craft short-circuits its permission checks on this single column, so no further changes were needed. The same primitive can overwrite any account’s password hash. Update to the patched versions (4.18.9 and 5.11.2) to get the fix. If you cannot update immediately, you can block front-end requests with %5Battribute%5D and [attribute] anywhere in the query string as a temporary mitigation.13h CVE-2026-1217698.5 HIG

——0A SQL injection vulnerability exists in a database migration script in flowintel. The migration process reads stored connector identifier values from the database and interpolates them directly into SQL statements without parameterization. An attacker who has previously written a malicious identifier value into the affected tables can cause arbitrary SQL execution when the migration is subsequently run during an application upgrade. - Requires prior write access to the database to plant a malicious identifier value - Triggered automatically during a migration or upgrade operation - Can result in unauthorized data disclosure, modification, or deletion Affected versions: flowintel prior to 4.0.021h CVE-2026-1246256.3 MED
