## What is CVE-2026-106513?

CVE-2026-106513 is a medium-severity missing authorization vulnerability in MISP, published on 6 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

MISP exposes critical infrastructure settings—specifically the Redis host addresses used by the core application, the ZeroMQ plugin, and the SimpleBackgroundJobs plugin—through its web UI and API to site-admin users. The background job workers trust raw Redis job payloads without additional validation. An attacker who obtains a hijacked site-admin session (for example, through a stored cross-site scripting vulnerability) can modify the Redis host settings to point at an attacker-controlled Redis server and then restart the workers. Once the workers connect to the attacker's Redis instance, the attacker can inject malicious job payloads that the workers execute, achieving arbitrary command execution as the worker account. Additionally, the download_attachments_on_load setting, which controls inline attachment rendering, was modifiable through the same interface, allowing a hijacked session to re-enable a feature that could facilitate further client-side attacks. The vulnerability requires site-admin privileges and a prior session-compromise mechanism; it does not require unauthenticated access. The impact is remote code execution in the context of the MISP worker process and potential data exfiltration through the attacker-controlled Redis connection.

Weakness: CWE-749 (Exposed Dangerous Method or Function), CWE-284 (Improper Access Control)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-106513 and fix it if it is affected.

What it is: CVE-2026-106513 is a medium-severity missing authorization vulnerability in MISP, published on 6 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-106513 in the wild and no public exploit code.

Affected product: MISP. 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.
