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.

PyCryptodome and pycryptodomex before 3.19.1 allow side-channel leakage for OAEP decryption, exploitable for a Manger attack.

Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template, potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.
