Amazon Linux 2 Security Advisory: ALAS2-2026-3333
Advisory Released Date: 2026-06-08
Advisory Updated Date: 2026-06-08
Mako is a template library written in Python. Prior to 1.3.11, TemplateLookup.get_template() is vulnerable to path traversal when a URI starts with // (e.g., //../../../secret.txt). The root cause is an inconsistency between two slash-stripping implementations. Any file readable by the process can be returned as rendered template content when an application passes untrusted input directly to TemplateLookup.get_template(). This vulnerability is fixed in 1.3.11. (CVE-2026-41205)
