CVE-2026-44363
📛 CVE Title
Unsafe remote resource fetching in expansion misp-modules
Description
MISP modules are autonomous modules that can be used to extend MISP for new services. Prior to 3.0.7, an unsafe remote resource fetching vulnerability existed in MISP Modules expansion modules. The html_to_markdown module accepted arbitrary HTTP(S) URLs without sufficient validation, which could allow Server-Side Request Forgery against loopback, private, or link-local network resources. Additionally, the qrcode module disabled TLS certificate verification when retrieving remote images, exposing requests to potential man-in-the-middle interception or response tampering. The issue was fixed by validating URL schemes, blocking local and private address ranges, resolving hostnames before fetching, enforcing request timeouts, and re-enabling TLS certificate verification. This vulnerability is fixed in 3.0.7.

The OPatch utility doesn't let you re-apply a patch already present, so it's quite easy to simplify the process by having a very similar process each quarter. Once I've got all the patches, I write a patching script for each product. For the database this includes OPatch and the latest database patches.
