CVE-2026-106513: MISP Redis host configuration exposure to site-admin users

CVE-2026-106513 · Severity: info · Published 2026-10-06

MISP, a platform for sharing malware and security threat data, allows site administrators to modify critical Redis server settings through the web interface and API. An attacker who compromises a site-admin account (such as through a stored cross-site scripting flaw) can redirect MISP's workers to connect to an attacker-controlled Redis server and then execute arbitrary commands as the worker process, potentially stealing data or taking over the system.

Quick answers

Is CVE-2026-106513 exploited in the wild?
No. Junglewise Threat Intelligence has no report of CVE-2026-106513 being exploited in the wild.
How severe is CVE-2026-106513?
Informational severity, published 6 October 2026.
Which products and versions are affected?
MISP Project MISP.
Is there a fix for CVE-2026-106513?
Yes: fixed in MISP commit 2ebf29f (redis host settings flagged cli_only). Until then: Flag the redis host settings (MISP.redis_host, Plugin.ZeroMQ_redis_host, SimpleBackgroundJobs.redis_host) as cli_only configuration options so they can only be set via server config or command line, preventing modification through the web UI and API. Similarly restrict the download_attachments_on_load setting to prevent re-enablement of inline attachment rendering by a hijacked session. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.
How is CVE-2026-106513 attacked?
It is attacked over the network, in a web application.
Am I affected by CVE-2026-106513?
Check whether you run MISP Project MISP. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

How to fix

  • Fixed in: MISP commit 2ebf29f (redis host settings flagged cli_only)

Flag the redis host settings (MISP.redis_host, Plugin.ZeroMQ_redis_host, SimpleBackgroundJobs.redis_host) as cli_only configuration options so they can only be set via server config or command line, preventing modification through the web UI and API. Similarly restrict the download_attachments_on_load setting to prevent re-enablement of inline attachment rendering by a hijacked session.

Technical details

The vulnerability allows modification of MISP.redis_host, Plugin.ZeroMQ_redis_host, and SimpleBackgroundJobs.redis_host settings via the web UI and API by site-admin users. Background job workers execute raw Redis payloads without validation; an attacker with a hijacked site-admin session can reconfigure these endpoints to point to a malicious Redis instance and trigger worker restart, leading to arbitrary command execution in the worker process context. The download_attachments_on_load setting is similarly exposed, potentially re-enabling client-side attack vectors.
