Amazon Linux 2023 Security Advisory: ALAS-2024-503
Advisory Release Date: 2024-02-01 17:56 Pacific
Advisory Updated Date: 2024-02-06 15:00 Pacific
Severity:
Medium
Issue Overview:
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. (CVE-2024-22195)
