Red Hat Security Advisory: fence-agents security and bug fix update

Moderate

A flaw was found in urllib3, an HTTP client library for Python. urllib3 doesn't remove the HTTP request body when an HTTP redirect response using status 301, 302, or 303, after changing the method in a request from one that could accept a request body such as `POST` to `GET`, as is required by HTTP RFCs. This issue requires a previously trusted service to become compromised in order to have an impact on confidentiality, therefore, the exploitability of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request bodies; if this is the case, this vulnerability isn't exploitable.

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

A flaw was found in PyCryptodome/pycryptodomex which may allow for side-channel leakage when performing OAEP decryption, which could be exploited to carry out a Manger attack.

CWE-203 - Observable Discrepancy

A cross-site scripting (XSS) flaw was found in Jinja2 due to the xmlattr filter allowing keys with spaces, contrary to XML/HTML attribute standards. If an application accepts user-input keys and renders them for other users, attackers can inject additional attributes, potentially leading to XSS. This misuse of the xmlattr filter enables the injection of arbitrary HTML attributes, bypassing auto-escaping and potentially circumventing attribute validation checks.
