codeql/python/ql/lib/CHANGELOG.md

0.0.11

Minor Analysis Improvements

• Added new SSRF sinks for httpx, pycurl, urllib, urllib2, urllib3, and libtaxii. This improvement was submitted by @haby0.
• The regular expression parser now groups sequences of normal characters. This reduces the number of instances of RegExpNormalChar.
• Fixed taint propagation for attribute assignment. In the assignment x.foo = tainted we no longer treat the entire object x as tainted, just because the attribute foo contains tainted data. This leads to slightly fewer false positives.
• Improved analysis of attributes for data-flow and taint tracking queries, so getattr/setattr are supported, and a write to an attribute properly stops flow for the old value in that attribute.
• Added post-update nodes (DataFlow::PostUpdateNode) for arguments in calls that can't be resolved.

0.0.10

Deprecated APIs

• The old points-to based modeling has been deprecated. Use the new type-tracking/API-graphs based modeling instead.

0.0.9

0.0.8

Deprecated APIs

• Moved the files defining regex injection configuration and customization, instead of import semmle.python.security.injection.RegexInjection please use import semmle.python.security.dataflow.RegexInjection (the same for RegexInjectionCustomizations).
• The codeql/python-upgrades CodeQL pack has been removed. All upgrades scripts have been merged into the codeql/python-all CodeQL pack.

0.0.7

0.0.6

0.0.5

Minor Analysis Improvements

• Added modeling of many functions from the os module that uses file system paths, such as os.stat, os.chdir, os.mkdir, and so on.
• Added modeling of the tempfile module for creating temporary files and directories, such as the functions tempfile.NamedTemporaryFile and tempfile.TemporaryDirectory.
• Extended the modeling of FastAPI such that custom subclasses of fastapi.APIRouter are recognized.
• Extended the modeling of FastAPI such that fastapi.responses.FileResponse are considered FileSystemAccess.
• Added modeling of the posixpath, ntpath, and genericpath modules for path operations (although these are not supposed to be used), resulting in new sinks.
• Added modeling of wsgiref.simple_server applications, leading to new remote flow sources.

0.0.4

Major Analysis Improvements

• Added modeling of os.stat, os.lstat, os.statvfs, os.fstat, and os.fstatvfs, which are new sinks for the Uncontrolled data used in path expression (py/path-injection) query.
• Added modeling of the posixpath, ntpath, and genericpath modules for path operations (although these are not supposed to be used), resulting in new sinks for the Uncontrolled data used in path expression (py/path-injection) query.
• Added modeling of wsgiref.simple_server applications, leading to new remote flow sources.
• Added modeling of aiopg for sinks executing SQL.
• Added modeling of HTTP requests and responses when using flask_admin (Flask-Admin PyPI package), which leads to additional remote flow sources.
• Added modeling of the PyPI package toml, which provides encoding/decoding of TOML documents, leading to new taint-tracking steps.
