CVE-2026-77761

A parser state isolation vulnerability in misp-stix could cause data from a previously processed STIX document to be retained and incorporated into the MISP event generated from a subsequent document when the same parser instance is reused. Several STIX 1 and STIX 2 parser components maintained...

CVE-2026-77755

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-2026-77761

misp-stix is a Python library for converting STIX documents to MISP events. A parser state isolation flaw allows per-document state (galaxies, galaxy clusters, passive DNS records, references, package titles, dates, and timestamps) to persist across conversions when the same parser instance is re...

CVE-2026-77761 Cross-Document Parser State Contamination in misp-stix

A parser state isolation vulnerability in misp-stix could cause data from a previously processed STIX document to be retained and incorporated into the MISP event generated from a subsequent document when the same parser instance is reused. Several STIX 1 and STIX 2 parser components maintained...

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-2026-77755

misp-stix is a Python library used by MISP for importing STIX 1 and STIX 2 documents. Two distinct flaws allow denial-of-service: (1) the import code used sys.exit() for parsing failures, which raises SystemExit (a BaseException subclass) that bypasses standard exception handlers, causing uncontr...

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-2026-77710

misp-stix (the MISP STIX import library) is vulnerable to STIX2 parser confusion and mass assignment (CWE-915, CWE-807). The import logic selected between the internal MISP parser and the external STIX parser based on untrusted metadata—MISP-specific tool labels (STIX2) or document title (STIX1)—...

CVE-2026-77710 STIX2 Parser Confusion and Mass Assignment Allow Unauthorized MISP Attribute Metadata Injection in misp-stix library

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...
