Astra Linux – Vulnerability in Mako

Mako is a template library written in Python. Prior to version 1.3.11, the TemplateLookup.gettemplate function was vulnerable to path traversal attacks when the URI started with // e.g., //../../../secret.txt. The root cause of this issue was an inconsistency between two implementations of path...

PYSEC-2026-4243 Mako: Path traversal via drive-letter URI on Windows in TemplateLookup

Summary On Windows, a TemplateLookup URI beginning with a drive designator e.g. C:/../../secret.txt or C:....\secret.txt bypasses the directory traversal check in Template.init, allowing reads of files outside the configured template directory. This is a third, independent instance of the root...

CVE-2026-102991 Mako: Path traversal via drive-letter URI on Windows in TemplateLookup

Mako is a template library written in Python. Prior to 1.4.2, on Windows, TemplateLookup.gettemplate in mako/lookup.py resolves template URIs with posixpath, while Template.init in mako/template.py validates them with os.path, which uses ntpath. A URI beginning with a drive designator causes ntpa...

CVE-2026-102991

The Mako Python template library is vulnerable to a path traversal flaw on Windows in versions prior to 1.4.2 . The issue stems from a discrepancy where TemplateLookup.get_template() uses posixpath to resolve URIs, while Template.__init__() uses os.path (which utilizes ntpath) for validation. Att...

CVE-2026-44307

A flaw was found in Mako, a Python template library. A remote attacker could exploit a directory traversal vulnerability by crafting a Uniform Resource Identifier URI with backslash traversal. This bypasses security checks, allowing the attacker to read files outside the intended template...

CVE-2026-44307 Mako: Path traversal via backslash URI on Windows in TemplateLookup

Mako is a template library written in Python. Prior to 1.3.12, on Windows, a URI using backslash traversal e.g. ....\ secret.txt bypasses the directory traversal check in Template.init and the posixpath-based normalization in TemplateLookup.gettemplate, allowing reads of files outside the...

SUSE-SU-2026:1819-1 Security update for python-Mako

This update for python-Mako fixes the following issue: - CVE-2026-41205: Prior to 1.3.11, TemplateLookup.gettemplate is vulnerable to path traversal bsc1262716...

Path Traversal

Mako is vulnerable to Path Traversal. The vulnerability is due to inconsistent slash-stripping behavior in TemplateLookup.gettemplate, where URIs beginning with // can bypass path restrictions and access arbitrary files outside the intended template directory, allowing disclosure of files readabl...

USN-8234-1: Mako vulnerability
