Detailsinfo

A vulnerability was found in MISP up to 2.5.46. It has been rated as problematic. This issue affects the function findOrgImage of the component OrgImgHelper. The manipulation of the argument Org.name with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality. The summary by CVE is:

The findOrgImage method in MISP's OrgImgHelper constructs a filesystem path by concatenating a user-supplied organization identifier with a fixed image directory and a file extension, then calls file_exists() on the resulting path. The organization name field is attacker-controllable through event import, which sets Org.name. Because no validation was performed on the field value before path construction, an organization name containing directory traversal sequences (e.g., ../../etc/passwd) would cause the path to resolve outside the intended org-image directory.  This yields two security impacts:   - an arbitrary file existence oracle, since file_exists() returns a boolean for any path the process can access.  - an arbitrary file read limited to files with .png or .svg extensions, because the resolved filename is returned and subsequently rendered or served to the requesting user. The vulnerability requires an authenticated user with the ability to create or import events that set the organization name.

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-95698 since 09/22/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details of the vulnerability are known, but there is no available exploit.
