CVE-2023-26449

Malicious script code can be executed within the victims context.

MEDIUM 5.4EPSS 0.73%

Does this matter?

Lower severity and a low EPSS score (0.73%). Track it; it rarely justifies an emergency change on its own.

Description

The "OX Chat" web service did not specify a media-type when processing responses by external resources. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We are now defining the accepted media-type to avoid code execution. No publicly available exploits are known.
