kestra-io/kestra

Kestra v1.3.3 and before is vulnerable to SQL Injection. The vulnerability occurs because user-controlled input from a GET parameter is directly concatenated into an SQL query without proper sanitization or parameterization. As a result, attackers can inject arbitrary SQL expressions into the database query.

Kestra is an open-source, event-driven orchestration platform. Prior to version 1.3.7, Kestra (default docker-compose deployment) contains a SQL Injection vulnerability that leads to Remote Code Execution (RCE) in the following endpoint "GET /api/v1/main/flows/search". Once a user is authenticated, simply visiting a crafted link is enough to trigger the vulnerability. The injected payload is executed by PostgreSQL using COPY ... TO PROGRAM ..., which in turn runs arbitrary OS commands on the host. This issue has been patched in version 1.3.7.

Kestra is an open-source, event-driven orchestration platform Versions up to and including 1.3.3 render user-supplied flow YAML metadata fields — description, inputs[].displayName, inputs[].description — through the Markdown.vue component instantiated with html: true. The resulting HTML is injected into the DOM via Vue's v-html without any sanitization. This allows a flow author to embed arbitrary JavaScript that executes in the browser of any user who views or interacts with the flow. This is distinct from GHSA-r36c-83hm-pc8j / CVE-2026-29082, which covers only FilePreview.vue rendering .md files from execution outputs. The present finding affects different components, different data sources, and requires significantly less user interaction (zero-click for input.displayName). As of time of publication, it is unclear if a patch is available.

Kestra is an event-driven orchestration platform. In versions from 1.1.10 and prior, Kestra’s execution-file preview renders user-supplied Markdown (.md) with markdown-it instantiated as html:true and injects the resulting HTML with Vue’s v-html without sanitisation. At time of publication, there are no publicly available patches.

Kestra is an event-driven orchestration platform. The error message in execution "Overview" tab is vulnerable to stored XSS due to improper handling of HTTP response received. This vulnerability is fixed in 0.22.0.
