## What is CVE-2026-73245?

CVE-2026-73245 is a medium-severity missing authorization vulnerability in kestra-io kestra, published on 11 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0-rc6, Kestra's cli/src/main/resources/application.yml serves Micronaut management endpoints on port 8081 without authentication even when Basic Auth protects /api/v1/** on port 8080, allowing unauthenticated GET /env requests to disclose resolved configuration and POST /loggers/{name} requests to change runtime log levels. This issue is fixed in 2.0.0-rc6.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
