AZL-105642 CVE-2026-103001 affecting package python-jwt 2.13.0-1

PyJWT is a Python implementation of JSON Web Token standards. From 2.11.0 through 2.13.0, PyJWT's PyJWT.mergeoptions method can modify a caller-supplied mutable options mapping when verifysignature is false. If an application reuses that same mapping for a later decode or decodecomplete call and...

python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

python: Quadratic complexity in os.path.expandvars() with user-controlled template

A vulnerability in Python’s os.path.expandvars function that can cause performance degradation. When processing specially crafted, user-controlled input with nested environment variable patterns, the function exhibits quadratic time complexity, potentially leading to excessive CPU usage and denia...

CVE-2026-51852

agent-zero 1.7, 1.8, 1.9, and 1.10 is vulnerable to Directory Traversal in python/helpers/filebrowser.py:FileBrowser.savefileb64. The savefileb64 method accepts user-controlled file paths without normalization or validation, allowing path traversal attacks...

CVE-2026-51853

agent-zero 1.7, 1.8, 1.9, and 1.10 is vulnerable to Directory Traversal in python/helpers/filebrowser.py:FileBrowser.init. The FileBrowser class initializes with the host root directory as the workspace, allowing the agent to access any file on the system without restriction...

AZL-105645 CVE-2026-102991 affecting package python-mako 1.2.4-3

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...
