A security vulnerability has been detected in StackStorm st2 up to 3.9.0. Impacted is an unknown function of the file st2api/st2api/controllers/v1/auth.py of the component API Key Handler. Such manipulation of the argument apikeyapi.user leads to improper privilege management. The attack may be performed from remote. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
Improper access control in Key-Value RBAC in StackStorm version 3.7.0 didn't check the permissions in Jinja filters, allowing attackers to access K/V pairs of other users, potentially leading to the exposure of sensitive Information.
Cross-site scripting (XSS) vulnerability in the Web UI of StackStorm versions prior to 3.8.0 allowed logged in users with write access to pack rules to inject arbitrary script or HTML that may be executed in Web UI for other logged in users.
In StackStorm versions prior to 3.6.0, the jinja interpreter was not run in sandbox mode and thus allows execution of unsafe system commands. Jinja does not enable sandboxed mode by default due to backwards compatibility. Stackstorm now sets sandboxed mode for jinja by default.
In st2web in StackStorm Web UI before 2.9.3 and 2.10.x before 2.10.3, it is possible to bypass the CORS protection mechanism via a "null" origin value, potentially leading to XSS.
Incorrect access control in StackStorm API (st2api) in StackStorm before 2.9.2 and 2.10.x before 2.10.1 allows an attacker (who has a StackStorm account and is authenticated against the StackStorm API) to retrieve datastore items for other users by utilizing the /v1/keys "?scope=all" and "?user=<username>" query filter parameters. Enterprise editions with RBAC enabled are not affected.
StackStorm before 3.4.1, in some situations, has an infinite loop that consumes all available memory and disk space. This can occur if Python 3.x is used, the locale is not utf-8, and there is an attempt to log Unicode data (from an action or rule name).
