CVE-2026-81820

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-2026-81820

Flowintel versions greater than 3.3.0 are vulnerable to HTML injection in the MISP case history timeline. Attacker-controllable MISP object fields (object UUID, name, attribute value, attribute type, comment, first/last seen, and IDS flag) were concatenated directly into HTML strings before rende...

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

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...
