Recent Palletsprojects Jinja Security Vulnerabilities
Jinja XSS via xmlattr filter bypassing auto-escaping
CVE-2024-22195
5.4 - Medium
- January 11, 2024
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.
XSS
This affects the package jinja2 from 0.0.0 and before 2.11.3
CVE-2020-28493
5.3 - Medium
- February 01, 2021
This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory.
Resource Exhaustion
In Pallets Jinja before 2.10.1, str.format_map
CVE-2019-10906
8.6 - High
- April 07, 2019
In Pallets Jinja before 2.10.1, str.format_map allows a sandbox escape.
