EUVD-2026-67131

Affected versions of Flowintel construct timeline HTML using attacker-controllable MISP object fields such as: object UUID; object name; attribute value; attribute type; comment; first/last seen values; IDS flag. Those values were concatenated directly into HTML strings before rendering. The...

CVE-2026-78380

RansomLook fails to enforce the privacy status of ransomware groups and markets when distributing newly collected victim posts to external notification channels. The post-processing logic checks whether an individual post is marked private but does not verify whether the group or market to which...

CVE-2026-78380 Private Group and Market Posts Disclosed Through Public Notification Channels in RansomLook

RansomLook fails to enforce the privacy status of ransomware groups and markets when distributing newly collected victim posts to external notification channels. The post-processing logic checks whether an individual post is marked private but does not verify whether the group or market to which...

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-2026-77751

A path traversal vulnerability existed in the handling of MISP object template names during STIX 2 import and MISP-to-STIX 2 export. MISP object names are passed to PyMISP's object-template resolution mechanism, which constructs a filesystem path by joining the configured MISP object-template...

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 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-2026-77761

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-2026-77755 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 Path Traversal in MISP Object Template Resolution During STIX Import and Export in misp-stix library

A path traversal vulnerability existed in the handling of MISP object template names during STIX 2 import and MISP-to-STIX 2 export. MISP object names are passed to PyMISP's object-template resolution mechanism, which constructs a filesystem path by joining the configured MISP object-template...

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...
