CVE-2026-56447
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk21th percentile - higher than 21% of all known CVEs
Summary
MISP allowed an authenticated site administrator to set the Kafka_rdkafka_config setting to an arbitrary filesystem path, potentially leading to arbitrary code execution with the privileges of the MISP process.
Risk Assessment
An attacker could leverage a MISP-writable location to host a malicious configuration file, posing a risk of unauthorized access and potential damage to the system.
Recommendation
It is recommended to restrict the setting to absolute .ini files located only in approved configuration directories outside the webroot and MISP upload targets.
Original NVD description (English source)
MISP allowed an authenticated site administrator to set the Kafka_rdkafka_config setting to an arbitrary filesystem path. MISP subsequently parsed the referenced INI file and passed its options to rdkafka. A crafted attacker-controlled configuration file could use rdkafka options such as plugin.library.paths to load an external library, resulting in arbitrary code execution with the privileges of the MISP process. An attacker could leverage a MISP-writable location, such as an uploaded file or administrative image, to host the malicious configuration file. The issue is fixed by restricting the setting to absolute .ini files located only in approved configuration directories outside the webroot and MISP upload targets.
