CVE-2026-77755 Denial of Service in MISP-STIX Import via Malformed or Oversized STIX Documents in misp-stix library

A denial-of-service vulnerability was identified in misp-stix when processing attacker-controlled STIX 1 or STIX 2 documents. The STIX import code used sys.exit to handle several parsing and loading failures. Because SystemExit inherits from BaseException rather than Exception, these failures...

CVE-2026-77751

CVE-2026-77751 is a path traversal vulnerability in the misp-stix library, affecting MISP object template name handling during STIX 2 import and MISP-to-STIX 2 export . Object names from untrusted content were not sufficiently validated before being used to construct a filesystem path for loading...

CVE-2026-77710

A vulnerability in misp-stix could allow a crafted STIX document to influence security-sensitive MISP attribute metadata during import. The STIX import logic automatically selected between the internal MISP parser and the external STIX parser based on metadata contained in the STIX document itsel...

CVE-2018-19908

An issue was discovered in MISP 2.4.9x before 2.4.99. In app/Model/Event.php the STIX 1 import code, an unescaped filename string is used to construct a shell command. This vulnerability can be abused by a malicious authenticated user to execute arbitrary commands by tweaking the original filenam...

CVE-2018-19908

Affected software: MISP 2.4.9x (pre-2.4.99). In the STIX 1 import path, the code in app/Model/Event.php uses an unescaped filename string to build a shell command. This enables an authenticated attacker to modify the STIX import filename to inject and execute arbitrary commands. Exploitation deta...
