- jinja2 - small but fast and easy to use stand-alone template engine
Details
Rafal Krupinski discovered that Jinja2 did not properly restrict
the execution of code in situations where templates are used maliciously.
An attacker with control over a template's filename and content could
potentially use this issue to enable the execution of arbitrary code.
This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2024-56201)
It was discovered that Jinja2 sandboxed environments could be escaped
through a call to a string format method. An attacker could possibly use
this issue to enable the execution of arbitrary code. This issue only
affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2024-56326)
It was discovered that Jinja2 sandboxed environments could be escaped
through the malicious use of certain filters. An attacker could possibly
use this issue to enable the execution of arbitrary code. (
