{"cve":"CVE-2026-44363","nvd":{"published":"2026-05-13T20:16:23.007","modified":"2026-10-26T14:10:00.130","status":"Deferred","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.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:H/SI:H/SA:H","score":5.8},"cvss_v3":null,"cwes":["CWE-295","CWE-918"],"references":["https://github.com/MISP/misp-modules/commit/01a522f2772fc31eeed379ccf23750c8a3d401db","https://github.com/MISP/misp-modules/security/advisories/GHSA-fhq3-2gf3-8f3j"],"products":[],"source":"nvd","synced_at":"2026-10-26T14:27:29.784594657+00:00"},"epss":{"cve":"CVE-2026-44363","score":0.00102,"percentile":0.00922,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-fhq3-2gf3-8f3j","url":"https://osv.dev/vulnerability/GHSA-fhq3-2gf3-8f3j","summary":"misp-modules has nsafe remote resource fetching in expansion","modified":"2026-07-13T16:43:14.327841976Z","packages":[{"ecosystem":"PyPI","name":"misp-modules","purl":"pkg:pypi/misp-modules","ranges":["<=3.0.7"],"fixed":[]}]},{"id":"PYSEC-2026-2650","url":"https://osv.dev/vulnerability/PYSEC-2026-2650","summary":"misp-modules has nsafe remote resource fetching in expansion","modified":"2026-07-13T16:31:51.153661131Z","packages":[{"ecosystem":"PyPI","name":"misp-modules","purl":"pkg:pypi/misp-modules","ranges":["<=3.0.7"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
