## What is CVE-2026-69262?

CVE-2026-69262 is a high-severity missing authorization vulnerability in Flowiseai Flowise, published on 4 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, `DELETE /api/v1/chatflows/:id` authorized requests with checkAnyPermission('chatflows:delete,agentflows:delete'), so possession of either permission was sufficient to reach the delete path. The delete logic then resolved the target record only by id and workspaceId and did not validate the target resource type, allowing a caller with only agentflows:delete to delete a CHATFLOW and a caller with only chatflows:delete to delete an AGENTFLOW in the same workspace. This issue is fixed in version 3.1.3.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2026-69262 and fix it if it is affected.

What it is: CVE-2026-69262 is a high-severity missing authorization vulnerability in Flowiseai Flowise, published on 4 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-69262 exists.

Affected packages and fixed versions:
- flowise (npm): affected all versions; fixed in 3.1.3
- flowise (npm): affected all versions; fixed in 3.1.3

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.
