## What is CVE-2026-97691?

CVE-2026-97691 is a medium-severity missing authorization vulnerability in get-convex convex-backend, published on 12 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Convex is an open-source reactive database for application developers. Prior to the self-hosted image published on August 10, 2026 and local deployment binary precompiled-2026-08-10-c0cb7ae, a malicious user can, in rare cases, perform unauthorized reading of deployment information from a Convex deployment. The maintainer has intentionally withheld the affected component and technical mechanism to protect self-hosted deployments that have not been updated, and no evidence of exploitation is known. Convex cloud deployments were patched automatically. This issue is fixed in the self-hosted image published on August 10, 2026 and local binary precompiled-2026-08-10-c0cb7ae.

Weakness: CWE-284 (Improper Access Control)

What it is: CVE-2026-97691 is a medium-severity missing authorization vulnerability in get-convex convex-backend, published on 12 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-97691 in the wild and no public exploit code.

Affected product: get-convex convex-backend. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
